Well - epp, if you shot kentmere to compare with tmax or delta you'll soon realize : kentmere is a real lousy film.
As others stated before you have to shot a lot of kentmere to find your individual workflow.
Kentmere is from it's characteristics in regard of tonals AND extreme fine grain indeed not to compare with higher priced examples. And on the other hand you may like it. Don't forget with bulk rolls you have a real budget film.
I personaly would like to compare kentmere films nearly with old Hp5 and Fp4 Ilford films (before emulsion improvements to + films). But this may stand only in concern with finer grain.
The complete tonal characteristic isn't
realy comparable with other films - AND THIS IS A GOOD THINK !
So many like kentmere therefore - other people like it from it's nice pricing.
TO me stands : If the nice price of kentmere will change in future or if it will come to the end of bulks with kentmere there will be no way to use this film.
TO me Ilford PanF has much smaler grain and Delta400 gives better push oportunitys. And then we should also compare with tmax!
But don't be afraid because Ilford has no
interest to start a "canibalation" campaign within Ilford bw film portfolio.
So kentmere should be the cheap offer today and it might be that in the future.
But caused from less demand I speculate on the discontinuation of bulk kentmere.
By the way a last question from interest also to many others : What about Ilfordpan 100/400 is it the same as kentmere 100/400 ? Think about
