A mempool that better reflects what miners are actually mining? Better fee estimation? More efficient bandwidth usage? Latest bitcoin core features like bitcoin-node and multiprocess (although not sure how much of that is landing in v30). I haven’t looked at the full changelog yet

Not worth it for me compared to hosting and distributing cp and shady vc smart contract projects on my harware, and the attack vectors that come with it for Bitcoin overall, imo. But sure, you do you.
