i have owned both . used to use the tarantula .. then bought the lycosa when i saw it available .. i sold my tarantula .. i love the lycosa .. prolly not helpful but oh well
I like the Tarantula because it's square and doesn't have odd sides like a Saitek, but tbh I haven't owned either and I'm just going to get a Lycosa, it's not so large.
The Lycosa's backlighting isn't as bright as the Tarantula's. I returned my Lycosa because it was too hard to read the keys in daylight. Everything else about the Lycosa (rubberized, laptop-style keys, slim profile) was fantastic.
I was going to get the Lycosa but then I read that only the wasd keys had anti-ghosting, therefore it may be a problem whilst gaming with other keys.
Anyone else heard of this?
