I am about to buy a fancy laptop primarily for the purpose of doing all my cryptocurrency stuff (but not mining).

Can anybody help me decide between Windows and Linux?  My main question is do wallets/nodes tend to be developed on Linux first or Windows first?  I want to know which platform Bitcoin clients, but also other cryptocurrency clients/wallets in general tend to get developed on first.

I am not an expert with command line (although I can use Linux in a basic way), so I refer mainly to GUI type wallets.  I am interested in software for Bitcoin, Ethereum, Monero, Factom, Synereo, Dash, Maidsafe, Storj, NEM, Sia and Lisk.  So Windows or Linux for these?
