Considering Naboo was peaceful with a volunteer security force it would make sense their fighters would focus a lot on aesthetics for "display purposes" while the Y-Wing was a utilitarian bulk fighter-bomber needed for war. Would make sense they didn't put too much stock into aesthetics.

Then you have the X-Wing which is simply the best and coolest looking star fighter in any galaxy. There is simply nowhere to go but backwards after that.
