ANC: Sony ULT Vs Sennheiser M4

Flipkart sale is live and I’m getting the Sennheiser Momentum 4 for around ₹17.5k and Sony ULT Wear for around ₹12k.

My main priorities are:
+ ANC
+ Comfort for long listening/work sessions

I’ve seen a lot of reviews saying Sony has better ANC, so I wanted to ask — even with this price gap(regular prices are ₹15k & ₹25k), does the ULT still beat the Momentum 4 in ANC performance?
And how do they compare for long-term comfort (2–5+ hours usage)?
