I might like the t2 better. Integrated ivg cover, hidden eye detent, only pump that offers t2 style handle...... Even the trigger frame is made special for the t2(to account for the half inch longer body due to the ivg being covered and the body being round.
T2 is duel arm pump...a lot more stream line IMO
The s6.5 looks like a s6 half blocked
Both great guns, it really comes down to what you think looks better....there is no right or wrong answer. I'd be more worried about what style trigger frame I wanted and color

also personal preference!
