LAbz...basically, if you had a really proper mic like a nice condensor mic that sounds great for vocals, or even a new sm-57 ball mic and then plugged it into a avalon tube mic preamp, routed into a high quality soundcard interface, or a descent mixer or DAW workstation, thats all you really need and your shits gonna sound butter...Sequence that shit in CEP or ACID, or CUBASE...SONAR is a another good one...and you got some sick trax....keep in mind as long as you also have enough RAM on board to handle your workload and multitrax w/ massive amounts of FX...your good to go.
Thats why ProTools is good...if you dont want to strain your computer because its taxing all your memory every time then protools is tight cuz its a rock solid HD farmcard sitting there by itsself doin tha job for you while yer computer relaxes....Thats tha only real benefit i see with PT...
Personally, i would jus invest in some nice converters, mic pre's, mic's, monitors, headphones, DAW workstations, and after all that - most importantly buy a shit load of ram....
