I have the Sony A6000, which is the older version of the A6300. I have found it to be a good combination of speed, size, quality and price. (As each new generation comes out, so far, I always end up keeping the A6000.)
There are a few things I would point out about the A6300:
1. The phase detection, video capability, viewfinder, and dust resistance are all better (in one way or another) than the A6000. If the price is within $300 or so, then get the A6300. If money is tight, and if the A6000 is a super bargain, then you might prefer having the A6000 plus money in your pocket.
2. The A6300 does not have a touchscreen. This is not really that big an issue because Sony touchscreens are not that great. But if you rely on that (or a joystick), the A6300 and A6000 have neither. They have a multi-function button inside a direction wheel, which I like, but some people despise.
3. The A6300 does not have IBIS. If you need stabilization, you have to go up to the A6500. Personally, I own the Sony 35mm stabilized lens, and it is good enough for almost everything I do, but the A6300 will want stabilized lenses.
4. The autofocus is very good, but the lock-on autofocus is not that much better than the A6000. To get really great tracking and lock-on, you have to go with the A7iii or equivalent, which is really a whole different level of camera.
5. The quality of the pictures is very lens-dependent, and anything other than "pretty good for the money" is very expensive. I have found that the kit lens and the "kit" 70-200 are both good for almost everything (except RAW of course), and for everything else, I use the 35mm IS lens, the 50 mm IS lens, or the 20mm, (which I think is not IS). Each of these lenses is cheap, and punch above their class for the money. The really great lenses are visibly better, but the improvement in quality is maybe 5% to 10%, while the increase in price can be 300% to 800%.
For example, the 35mm 1.8 is stabilized, sharp (at anything over 2.8), has great color, weighs 5 ounces, and costs about $400. If you want to get anything sharper, you have to either get a huge lens, lose the 1.8 max, or pay $900. (Or all three.) For the time being, the 1.8 OSS is perfect for me.
6. Even if you need critical sharpness, the A6300 can still deliver, but you will have to make some other compromise in lens size, price, or speed.
Happy shooting.
