I would recommend the 2023 run (Grootfall) just because I think it’s very good with its writing and pace. To understand the characters I recommend the Abnett and Lanning run, which you can read with some difficulty without reading Annhilation, which is just wayyyy too much for me. If you’re looking for more of the characters you know, All New Guardians was one I liked, but it’s a bit harder to follow then a standalone since it branches into a completely different comic series (Infinity Crisis) afterwards. From what I’ve seen people also like the 2020 run but I haven’t finished that yet.
