What I like the best is one thing, what is free or cost money, is another, and what the personal computer will handle is yet another. Yet one more is the desire to keep the process as simple as possible or having the ability and desire to tackle a complex processing program and learn it over time.
Since you appear to have the speed, RAM and graphics it comes down to a willingness to purchase software or a desire to remain expense free and settle for less capability.
For paid for programs I like Adobe, Capture One, Vegas. Filmora Wondershare, and Photoscape.
