I also am on the hunt for an amplifier and I've been looking at an IBANEZ TBX150R with the matching cabinet. This thing is an absolute beast. The amps you suggested it really depends on what your taste is. You can say you play a lot of Creed and stuff but I find that sometimes I finally get to a point where my guitar sounds exactly like the song (I play a lot of Creed/Alter bridge too) and I find I prefer something a little different. Some amps will make jump up and down with excitement and some will make you want to pop out your ear drums. You're best bet is to just read a lot of reviews about each amp and try them out (Guitar center has a good return policy if you don't like what you get even if you had to order it online). Also keep in mind, no amp is the perfect amp. Some will sound better in different ways. Some sound good for clean, some better for distortion and some better in between. Some only sound good for one song and some different. Of course you can't get 19 amps but you should be able to find something you like.. Make sure you spend a good amount of time with each one. Also don't be so crazy on an amp just because it has a good name. Personally, I don't do Marshall amps. They sound a bit to tinny for distortion. For blues they sound great but that's not my style of play. There's an amp that will be just right for you. The only person who can help you decide whats right for you is... well you!
