It always depends on the context and your needs.
If your host is the very core of your studio and/or you need it to run virtual instruments, work w/ loops, do extensive midi work and need a self-contained all-inclusive solution, Pro Tools probably isn't the best option.
For some people, the absolute best solution will be Ableton Live. For others, Mainstage on a laptop. For others it'll be Sonar or Cubase or Reaper...
For me, MIDI and sampling + creating sampler instruments is crucial - and
nothing even comes close to Logic and EXS-24 in that department. I do own Pro Tools (native), and while I like mixing in PT, overall, it isn't the right app for me. Same for Cubase and Studio One.
Though Avid did try to get their share of that swiss-army knife market, Pro Tools just isn't the best tool for that, imho.
OTOH, it has its strengths - it has to. Which is why it's still in virtually every major league studio.
Even among the users of the same products, you'll have a tough time finding two people having the same workflow. I've used Cakewalk products for a decade and there are certain features which are crucial to other users which I've never even touched. Yet, users from every horizons and w/ every type of needs managed to bring project to completion in the same app.
There are some scenarios where a Fender twin is the absolute best option - who in their right mind would try to put it down simply because it doesn't offer 30 different amp models and effects like a Line 6 amp or a software amp sim? It always depends on the scenario...
