I still prefer the Jeeves series, simply because the characters seem to 'leap off the page' more for me, but the Blandings books also possess a certain charm.
Anyway, Wodehouse really only wrote two books didn't he? The Jeeves series nearly always follow the same basic storyline (substituting a cow creamer for a statue or one potential fiancée for another one) as do the Blandings ones.
If you fancy something else, light, very funny and extremely well-constructed, Mikey, get hold of a copy of 'Let The People Sing' by J B Priestley. It's a masterpiece of story-telling.
