Well,
You are deciding between a $200 stripped down, branded phone and an unlocked $700+ phone that is more a proof-of-concept than anything else.
Obviously you're interested in a touch screen phone. The first thing you should do is decide between the two technologies:
Capacitive
or
Resistive
-- Look them up, weigh the pros and the cons. This is the SINGLE most important choice when choosing a good touchscreen phone. It is (afterall) how you will interact with your device 90% of the time.
Now weigh OS, Screen Size and Features.
If you're looking for a cheap touchscreen phone on At&t, I recommend the Eternity by Samsung. If you're looking for a touchscreen and you have $0, the Vu is... allright.
TouchFlo 3D is good on a handset with enough power to handle it, every HTC with TouchFlo available domestically is underpowered and is sluggish when handling TouchFlo.
HTC is a real good company but the Fuze is pathetic and the 4G MAX is a novelty.
Get a mite bit more specific about what you want out of a phone and we'll be able to zero in on exactly what suits you.
