I think that loyalty to protools is waning as whole. The reason I didn't use it was the fact that it locked down a lot of my equpiment choices. A bit like choosing a mac over a pc, macs do what they do wonderfully but I can make a pc do anything...
Currently the studio here is based around cubase sx3 and it works great for the stuff I do. As this is a school its understandable enough for all the kids to use (even year 7s come up with some great stuff) and powerful enough to do professional work. Ok.. not mastering grade here but that can always be farmed out to a studio built for it!
The rest of the kit is
Yamaha 01v96 with a 16i/o a/d firewire addon card.
motu24/96 via adat
You know.. as far as important stuff goes... thats about it. I have lots of outboard, that I almost never use.
I have a tape 4 track, that never gets used.
Various midi outboard and keyboards, that sometimes get used.
So apart from a decent set of mics and some bad*** cableing thats all you need really... anyways.. OT somewhat, this wasn't list my kit day! What was the question... oh yeah....
Yes, there are alternatives to protools and these days when everything is 24/96 at least then the differences are very quickly becoming academic. As I often say if only 0.0004% of the listeners are going to notice any difference, why the hell did I just spend £20k and 400hrs installing my new flashwhizz2000?
Oh and if you want a great argument, try the logic vs anything else with a mac user
