UDub CS is very well-respected, but I heard that Bowdoin has pretty good CS for a LAC.
If costs aren’t an issue, if you still aren’t sure that CS is for you, I’d go with Bowdoin.
BTW, in terms of prestige and all that, UDub CS is well-respected in the software world, but people not in that world may not know anything about CS rankings and UDub CS may hold no prestige to them. Bowdoin is an Eastern LAC, and definitely well-respected by those who know Eastern LACs (movers and shakers on the East Coast and some other mostly-well-educated people). Folks who don’t know much about LACs (other than those near them) may not know anything at all about how good it is.
