Obviously it would help a bit to know your tastes?
But on Friday if you’re after some techno then Tresor would be a decent bet - Carl Craig & Mike Banks upstairs and some decent DJs down in the cells. They’re usually alright for letting in tourists, though if you have it then wear black just in case: https://ra.co/events/2164814
On the Saturday then Else could be fun, especially if you’ll be already in the mood for partying from the early evening; it’s an outdoor venue but with a roof, plus some views on to the river Spree, doors open late afternoon, get there in time for sunset. Bouncers can occasionally be strict even with tickets.
Efdemin and Luigi Tozzi should be familiar names to a few on here. The night should range from tech-housier techno, to more looped, hypnotic techno. One of the DJs on the bill is actually someone I once met aages ago at a Digweed gig in London, though they don’t really spin similar music to Diggers ha: https://ra.co/events/2134832
