Only two are obsolete, the other 14 are commonly used. Oh, and there are two with a second optional form to compensate :) In English it's mostly done with mandatory pronouns and ancillary verbs (have, should, will) and only present tense is different for third person, everything else is just the same. Of course the pronuntiation and the phrasal verbs ruin the party. You must be very proficient already, so you don't realize how many irregular verbs there are. I won (ex aequo) a competition at school and it was very hard. Ser (to be) is specially pathological, stealing from ir (to go) half its conjugation, but hardly the only common irregular verb: have, go, say, walk, want, put, know...
