QuantMogul desktop vs web — which parts are actually worth paying attention to?

Trying to map the QuantMogul surface honestly for a retail workflow:

• Web: research / agentic / marketplace-ish views
• Desktop: walk-forward, Monte Carlo, heavier local backtests

What do you personally run where?
I currently WFO + MC on desktop, then sanity-check forward survival ideas against WorldBotRank on wobr.ai. Curious if others split the stack differently, or if Python (backtrader/vectorbt) still wins for you on cost/control.

Cons of each path appreciated.
