I like the ones who were just his children. That makes sense to me. Lyra, Skaar, and Hiro-Kala were the only ones i needed. Though, Hiro-Kala was literally only around for a minute, and Lyra and Skaar didn't last long.
Lyra was at least different enough, with anger being her impediment instead of strength. Skaar was neat and I stand by that.
I didn't need all the secondary hulks. I've never been that into Red Hulk.
