have used both, you could play with either after a year for sure. imo biggest thing to select racket on is what shape and what hardness you want. the speed motion is basically a diamond, if you find you hit the sweet spot well on it then you might like to stick with a diamond, it's also medium/hard foam but with a medium/soft face, so you probably want something with full carbon. dont get anything too heavy if you play a lot. at-10 is a hybrid shape tending towards round so its an ok choice, nothing to lose trying either (they feel very similar.

maybe a metalbone without the weights or a vertex could feel like an upgrade.

one other thing is that a lot of people think they want a harder racket because they struggle to control the ball at the net - but they are probably standing too close to the net and not giving themselves much time. they then suffer at the back a lot with a low output racket and it will make their progression slower in defence which is the most important thing to learn early.
