Shadowheart Karlach Lae'zel and Halsin are my most favorite characters (in that order), though I also like others too (with 1 exception: my Karlach party haven't been able to talk to Minthara once recruiting her since weeks ago and I'm now waiting for a response from Larian on my bug report regarding that).
Lae'zel is a significantly better character than I initially thought/misjudged. I genuinely like her, especially after she's been toned down a little with Patch #5.
