i havent seen tati play but up to this stage going on results and who is challenging the top players more i would say masha, having said that tati hasnt played many top top players so its kind of hard to tell. but tati has had some luck. i guess to look at it another way is that tati has had more opportunities than masha with the french open WC's etc but im not really sure who is better since i havent seen tati play, but masha is very talented and for someone to get the results that tati is getting at her age they also have to be quite talented.tati is one of the juniors i want to follow through to the end of her career, also sharapova, krajicek and vaidisova. these 4 players imo are all going to be very good and are all extremely talented.
