Flown several DJI models, PowerVision Eye & Egg, Autel EVO, and Yuneec H Pro, H920.
As several have indicated, there are multiple benefits of each; your available funds & needs would narrow that down.
The H Pro is a great stable platform, handles windy gusty days nicely; you've probably read various threads on various landing procedures... some find it a little challenging to consistently land. The preference of the controller style has it's roots to what you've previously used most or adapted to quickly. My personal opinion is the ST16's screen is poor in bright light and I find the controller on the cumbersome side due to width, but I think that's mainly due to me being used to narrower RC's by other manufactures. The H Pro uses an older excellent camera and is limited in software app options, currently I believe there's 1 3rd party app beyond the default app on the controller. That isn't a negative unless you desire additional functionality. The new H Plus is a step up in camera & electronics adding to stability, control, and camera.
The PowerVison units have a roughness to them... The Eye flies & controls less fluidly compared to the H Pro and other Platforms. The PV Eye is an impressive machine on paper, but the connectivity isn't always as quick as desired.... I suggest watching a few YouTubes not by PowerVision. It uses an older method of separate radio, transmitter modularity, and the screen is limited to Phone size mount. The PV Egg... well it's just a fun one to own, it flies sluggish and not meant for much other than just being a Unique Shape with a 4K camera... but shares the connectivity design & operation. The PV Eye will probably be the most "closed" platform, I don't think 3rd party is involved with the platform. To clarify, I don't own a PV Eye... looked & flew one several times and decided to not purchase.
The Autel EVO after the last 2 recent Firmware updates is actually a very nice craft. Very similar to Mavic design... I'd call it a Mavic 1.8+ version. It has a very nice compact controller with a screen that can be a visual or information console screen depending if you have a phone or tablet connected. The EVO is noisy, if you've heard the Mavic Air the EVO is similar but at a lower tone pitch. There is a 3rd party mount that will allow the EVO Radio to mount a tablet if larger screen is desired.
Another EVO incentive... they are currently offering the EVO discounted to $999, and adding the Bonus Pkg: 2 additional batteries, 1 prop set, and travel bag, and a $100 BestBuy Cash card... that's about a $320-500 discount depending if the EVO goes back up to $1199 or remains at $999. But saving $220 on Bonus Pack & $100 BB Card is a sweet deal.
One advantage all the above have in common is non-DJI NoFlyZone software controlled restriction and no need for Internet connection for various feature activation. Although, always an unknown, this could change with a FW upgrade to anything adding possible restrictions. I'll be adding a Yuneec H520 soon, 1 reason is the avoidance of the DJI NFZ software.
The Mavic 2 - Pro or Zoom is a small craft as previously indicated. It's native color is poor for distant visibility, adding a skin can greatly improve. It is considered a quite craft, I personally find it the lowest noise craft, held previously by the MP with quite blades. I've had it 50' on realty tasks in tourist towns multiple times and it's gone unnoticed by surrounding people. There are hundreds of YouTubes expressing it's strengths in video quality, stability, noise, etc. I'd highly suggest you watch several videos. It's not officially supported, but you can easily swap the Pro & Zoom cameras and the firmware recognizes both without issues. It's been out long enough now, the Zoom Gimbal or Pro Gimbal is easily available on eBay.
The Mavic 2 transmission - OccuSync 2 provides a very stable transmission & fluid video.
One advantage if you're wanting to add devolped specialty software or simply want to explore low cost optional software: Litchi, AutoPilot, Mapping, Roofing, etc... the Mavic has hundreds to choose from, most under a few $bucks.
The Radio controller is very compact, and provides the ability to use pretty much any size screen in iOS or Android you prefer. The Ultra Bright CrystalSky screen will also mount, a pricey option but provides a clear screen in bright Sun. For excellent tablet view, the Hoodman screen hoods are great too.
I also own all the Mavic's, Inspire 1 Pro & Raw, Inspire 2, Matrice M210, M600Pro and few others. The Inspire 1 is an old craft, but still highly supported in 3rd party and probably the most adaptable in Camera options: X3, Z3 zoom, X5, X5Raw and XT 640 Radiometric Thermo. The I1 is a no-frills performer, lacks the modern avoidance systems and complex sensitive electronics; it isn't the best of the Best for 2019, but it's always capable to perform the work. For the obtainable price in today's market, it's a great buy. If you look for a I1, focus only on the V2 version with updated motors, props, retract rack, X5 mount, better carbon.
I'd agree the H Pro would be a nice choice, the older Inspire 1 Raw, and the Mavic 2 Pro or Zoom.
