noob question

I've some eth on a ledger, which I also connected to Metamask by following Ledger's procedure.

I was wondering: ledger has 24 keywords, metamask only 12.

Assuming that I've my 24 words, If I loose or break my ledger, do I need a new ledger to be able to have access again to my eth or can I use a software wallet as Metamask (without ledger) or an hardware wallet from a different supplier?

Thank's in advance
