Flown Jungmann & Stampe. M-m-mmmm to both, & they fly nicer than Tigers, (more precise & controllable) but on balance I'd go for the Jungmann. Grouping sounds eminently sensible - not just the purchase y'know, its the running costs...
I would have thought Citabria/Super Cub would be better for single ownership (assuming the sort of budget you're suggesting.), purely from the maintenance aspect (engine& airframe spares, engineers knowledge, etc etc).
According to where you are, check out your local engineers' expertise, knowledge and preferences - this could be crucial to keeping it airworthy whilst minimising time & expense scrounging for rare parts & specialists.
