Default which amp to build?

can someone advise me on which amp to build?
I am looking to build a mono class D amp and have seen recommendation for the TPA3106D1 and the TK2050.

They are both recommended but I dont want to build both. What do you recommend? They both seem equally simple and cheap and both meet my specs. Its a choice based on a feeling now, but i have no feeling one way or the other.

Hard to say without seeing the schematics.

They look like they'd be about the same.

Can you solder smd? Do you want to use it or is it just a gadget? Can you etch/drill? Do you have a PSU and if so, single or symmetric?

Hi thanks for the responses.
I can solder SMD I will use it but I'm not an audiofile, but if one is better i might as well make that if its the same every other way.
I have access to a board router.
I have access to a desktop PSU but plan to run it off a battery if it makes a difference. I was planning to just buy a battery charger. I'm going to deal with the battery charging and circuits at a later date

If you dont want to do smd then you could consider an irs2092 class d amp.
It works fine so long as you keep the layout tight and the circuit well decoupled.
