Power amplifer difference

[jacobsetti]

What is the difference between these amps
Is schematic same??
LJM Assembled L15DSMD 250W Digital mono amplifier board IRS2092 IRFI4019H-in Amplifier from Consumer Electronics on Aliexpress.com | Alibaba Group

YJ IRS2092 200W Class D Amp Mono Amplifier Board YJ-in Amplifier from Consumer Electronics on Aliexpress.com | Alibaba Group

Which one would be better for inserting it into speaker box

I would fit the LJM as it has output FETS and could be upgraded in power.
