Vidiot is the quickest way to get going with a lot of options. It’s great. And having another piece of gear with an LFO and filter, like the Neutron, will be nice with it (I use a Mother32 similarly).
But the Vidiot is a serious gateway drug. You’ll want more.
I really like the Castle Shift Register. And the Sandin Function Generator is great, so you may want to keep an eye on reverselandfill’s Triple FG project.
But what makes sense for you depends a lot on what kind of stuff you want to make!
