^ Which Samsung did you try?
Little things like which ROM version you have can make a difference, but Samsung's interface isn't the best... it's better than the pre-WinMo 6.5 defaults, but not the best of the bunch. Plus, those widgets that you see in all their advertisements and even on the product packaging are all totally useless and gimmicky.
But the good thing is WinMo is fully customizable. The US Omnia (i910) should be a good choice, I think it's $199 on contract from Telus? You can grab and put 6.5 onto it, it makes the whole thing much nicer to use (and does away with most of the Samsung stuff).
