Default Difference between tpa3255 and tas5630

I am looking at chinese amplifiers from aliexpress and can't really tell what the difference in performance between these 2 chips is. They are similarly priced, tpa3255 being perhaps 10-15% more expensive

Could someone tell me what the difference is?

The TPA3255 is the later design & most people seem to agree it sounds better. The TI & 3Eaudio are the best sounding 3255 boards though.

Cheers

I'm building a boom box with one of these that will be powered with 18650 lithium batteries.

Cost is a factor, so I bought this tas5630:
UNISIAN TAS5630 2.1 Audio Amplifier Board 2X150W+300W Digtial 2.1 channels Class D High power Amplifier for Home theater system|Amplifier| | - AliExpress

But I was wondering if I should have gone for a tpa3255 instead.

Do you think boards based on tpa3255 are likely to be more efficient in terms of energy consumption?
And would they have more protection built in than the tas5630? i.e. oversurge protection, overvoltage etc.

Thanks!
