HTC Sense Mail App or Gmail App?

G'day lads,

I recently got a HTC Sensation and I have two email accounts, an exchange account for school and a personal Gmail account.

I've tried importing my exchange account into my Gmail account but I cannot seem to get it to work.

So my question is, would you reccomend I use the Mail app for my exchange account and the Gmail app for my personal one, or just use the Mail app for both emails. Would I lose out on anything? I'm not really a hardcore Gmail user and I don't use labels.

Regards, Seakip
