me and my best freind are no vets by any means of the word but we both play UM. i actually started the notion of building second company before the 5th edition codex came out then it came out and the idea stuck. which eventually got my friend stuck on it too, so it's bit of a race to see who builds it first. but yeah i'm thinking of starting some small tiny 500 pt. armies of other chapters but i don't plan on ever useing other sm armies that have codexs with my ultramarines expecially taking my UM and useing another codex and calling then some thing they are not. but i really don't get why people knock them about os much all i can really come up with is that they are jealous that they are the face of the game and they always are one of the first of the codex releases. it really dosen't matter wether you have a new codex or not it may be really nice but you can win with any and every codex and a bit of luck with rolling some thing i don't have
(exhibit A: i had a enemy sm tac sergeant out in the open we were playing kill points, he already had 2 on my and i had 1 on him i shot a rihno, a land raider crusader that moved at combat speed, sternguard squad with missle launcher, yes i did shoot krak, and the sergeant took all the hits soaked up every single one of them and wasa still on the board because it was the last turn! no if thats not bad rolling i don't know what is!) and i loaned all his men to him so he could play! so the sergeant was mine!
