Preferably one with a mod manager/download client. Vortex is kind of janky but it did the job. I’d prefer not to manage any of this stuff manually, like cavemen. it’s been decades you shouldn’t need to do that

MO2 can do anything Vortex can, and in fact, Stalker and Stalker 2 modders prefer it. The files just need to be hosted elsewhere. A lot of modmakers advise against using Vortex to begin with.
