If you can afford it, I'd say yes. Most components will be just a little bit better and perhaps a little bit stronger. I think the 7200FX has a suspension seatpost, while the 7300FX does not. At that price point, I'd strongly suggest against a suspension seatpost.
Just make sure you've left enough budget for the accesories you'll need, if you don't own them already - helmet, gloves, tire pump, spare tubes, patch kit, water bottle cage, cycling shorts etc.
