Looking for recommendations for next motorcycle

Just found this sub, asked in r/motorcycles and didnt get too many recommendations so hoping you guys have some more. I currently have a cb300r and will likely keep it for another year or so. I'm looking into upgrades now to potentially catch a good deal in the interim.

I'm looking for bikes in the 10-15k range, capable of 150+ mph in straights but also good in the twisties. Currently looking into the zx6r and aprilla 660. Kawasaki seems like the more reputable brand and the bike will last longer, with cheaper maintenance, but I also just really like the look of the aprilia. From what I've seen spec-wise the zx6r seems like the better choice, but I'm curious if there's a bike out there with the tone and look of the aprilia but the power at or near that of the zx6r. Open to liter bikes and nakeds if they meet the price and power criteria respectively.
