The top pair look the most solid, I wouldn't worry about loosing the stuffing... it happens in all gloves.... My right looks like it has a tuma at the moment... :P

Those everlast ones look nice, I like the way they've been cut, couldn't tell you what the rubber is like... hopefully its dunlop... I'd think so.

Nice big straps too so you can do them up easily... laces are suicide unless you want to piss every one in the gym off...
