Anyone familiar with flat roofs- coating vs new

I live in a townhome style home with a flat roof. Current roof is an old hot tar roof. I’ve been getting coats on replacement. Most quotes are modified bitumen CertainTeed Flintlastic.

However one contractor mentioned coating it with a silicon elastomeric . He said it would last 10-20 years which seems to be what the modbit would be . Please see below

What would be the better option ? Is a silicon covering really that good? Or should I go with the Flintlastic.

Thanks

Looking for help with a flat roof

Some have said they can go over my existing roof. Others have said I should rip down to decking. Is it OK to go over existing roof? Current roof is an old “mop down” hot roof. Also said they will install new copper drain box 4”.
