Turkish Airlines Miles&Smiles - Any difference between A330/343 on ORD-IST in Y?

Might take advantage of excellent one-way fares: Nearly anywhere in the US to IST is US$522 including taxes for June travel!
Some ORD-IST flights use an A332, others an A343.
Any difference in Y? Looks like on Seatguru A343 might have 1" more seat pitch; do both planes offer in-seat Video monitor? If so, I'm surprised!
Thanks in advance.

Seats on both airplanes are almost identical. 330 seat width is half an inch more and some rows on the 340 have 34 inches instead of the 33. Both airplanes are extremely comfortable and both have AVOD. Always a pleasure to fly TK especially on long haul.
