Cyclone 10 LP dev board or spartan s7-25 dev board?

Hi…

Cyclone 10 LP has nearly 25k logic cells and s7-25 has 14k LUTs which is nearly 23k logic cells is that right?

So i m having a doubt on selecting …,Like which is good for long term and future proofing and which can handle more complex projects.

And the next doubt Lets say i m going for s7-25 ok! where can i find warranty information ?
