In my opinion you're not just buying the film but should also invest in
the holder that matches the film you use.  I've not used Acros in 4x5 (I
shoot some FP-4 and some Tri-X--neither available pre-loaded since film
packs went away--and again--yes I'm that old) but feel that Tmax 100 is
an excellent emulsion in all available sizes, just a bit fussy for the
casual user/beginner so if I were to buy one holder to use with one film
if would be Fuji.

I use Kodak TMAX 100 film so I bought the Readyload holder and have
been using the ready loads occasionally. They cost alot more per sheet
but they are worth it when you have to carry your gear. It is
relatively easy to carry 50-75 sheets of film. I rarely need that much
but even 20 sheets of regular film in carriers is onerous.

I understand that Ilford cannot manufacture readyloads because of
expense and patent issues. Maybe when Koadak stops making readyloads
they will sell the gear etc. to Ilford.

TMAX is more readily available than Acros also.

I don't own a 4x5, but I shoot Acros in 135 and 120.  It's beautiful
stuff.

I will say, though, that it typically takes more developing than other
films.  I use a rotary processor, so I'll typically have to take
10-15% off the base time on the chemistry's chart due to the constant
agitation.  Acros gets the full time, every time, especially in 120 -
it's more of an ISO 64-80 film.  Anything less just gives me a neg
that's way too thin.  I use Ilford DD-X primarily, so YMMV with other
developers.
