I prefer slottas, perhaps because I started with GW figures and stayed with them a long time. I find integrals awkward, and usually remove them and base them on slottas, at least until now, as I'm collecting forces for Sharp Practice and couldn't face reomving 30 integrals from my 95th rifles, 3 boxes of French Naps, two boxes of British etc. I'm using the 20mm square Renedra bases.
