what RPC are you using for reliable on-chain transaction delivery?

Been building bots for a few years when i do think i need something automated. Started with an AtomicHub marketplace bot, then a grid trading bot for Solana tokens I hold that is still running on an old pc. Last November I built one for ORE mining, first as a Chrome extension on ORE official webpage, then moved it to a backend deploying directly on-chain.

Recently decided to open it up to public and needed a private RPC that's fast, low-latency and reliable. I can't afford to miss transactions in a short deploy window. Currently on Helius Developer plan and it's holding up fine for now, but I'm wondering if there are better options at a similar price point before I commit long term.

Anyone recommend a different private RPC provider that's still reliable? Feel free to ask if you want more details about the setup.
