I will always recommend T3 Code, it is by far the best one I have tried that isn't glued to a specific model provider. Trades blows with Codex / Claude Desktop in terms of features. All of the other multi-provider orchestrators have not been keeping up with Claude Desktop in particular adding features at lightning-speed, but T3 Code somehow manages.

(I am building my own tool in this area and I literally downloaded and tried all of them as market research)

I second this. T3 code especially for remote machine workflows is unmatched.
