I personally don't like Premiere much but it is useful for some stuff I work with. I also use Photoshop, After Effects and Audition a lot so it does not hurt to have the Premiere come with the same package.
Honestly speaking, I think Premiere is pretty much piece of crap program for most professional uses, it is not very reliable and it is pretty awkward and slow to use for large scale editing I think, especially on mac. The main purpose for the whole program as I see it is for fast turnaround one-man-band video guys who do low budget commercials and indie films etc. where it is useful to have lots of basic features in the same program so that you can edit and finish completely within Premiere even if it's very slow to do (for example grading with Lumetri) and unpractical at times (but still useful for beginner indie guys who don't want to learn to use any other programs and don't know any better nor have high standards for end result...)
FCPX lacks most of the essential features I need so I rarely use it for actual editing. It also does not have very good integration with any other essential pro programs. It is pretty much "editors love it, all the post persons hate it" program .
Resolve is now more reliable than the previous versions so I would consider it "pretty ok" for basic editing. At least it is fast to grade the end result then even when the editing is not super fast with it.
BTW, I really love Audition for basic sound work like making of docs and similar stuff. It also seems to be pretty reliable in my use. The funny thing is, it is NOT originally an Adobe program... it is based on CoolEdit from the early 2000 something which Adobe bought and just added new features when keeping the interface and other stuff the same. Maybe their 'anti-Midas touch' thus did not reach the core of the program and it is a bit better working than other Adobe stuff
