You really should watch the newest ones. So much has happened, with the Turf War (Unrelated to Splatoon) going on in the shopping district, and Mumbo and Iskall starting a new company better than Sahara (Which was a mega company that Mumbo, Iskall, and Grian started in the middle of Hermitcraft season six.) called Pacific, and so! Much! More!
My favorite hermits are MumboJumbo, Iskall85, GoodTimesWithScar, Bdouble0100, Grian, Falsesymmetry, Xisuma, and a few others whose names I cannot remember.
(P.S. Does anyone remember who the owner of Hermitcraft is? Far as I can remember, it's Xisuma, but I'm not 100% positive.)
