Short answer: yes.
LOnger explanation. Film have textures (aka grain) that are different from film to film (eg. Fuji Acros 100 film looks very different from other 100 type film), some of the grains are different eg, T-Max has "T" grains which looks very different from a more classical film Tri-X. Tri-x is more pushable, can be iso rated at 200 to iso 1600 while giving acceptable tones. On the other other hand, a film like agfa apx 400 has alot of fans because of the "blackness" of the images, however it isn't pushable past 1 stop from iso 400.
To confuse you further, different film reacts differently with different developer. However, there are different types which affects grains, sharpness, details.The most popular ones here in Singapore is Kodak D76 (Ilford's ID-11 is the same developer), which is used in Fotohub and I suspect at Konata. If you use T-MAX 400, try with the T-Max developer, the effect is very nice.
While some people do not like grain, i think grain makes film special as digital do not have grain built in by default.
Here's a picture from a classic film, plus-x, developed in a grainy developer (PQ universal), shot on a nikon fm with 35-70/f3.5 lens.
my suggestion is to enjoy the film since i doubt if all of the them will be around in the next 5 years.
so if you can afford it, buy a few, test shoot the first roll at various iso and then have it professional developed,
and see how much you like the photos. Indoor and outdoors has different effects as well.
if you like it, consider doing self-development. for me personally, my favorite 100-200 film is plus-x,
my favorite 400 film is fuji neopan 400. for 120 film, it is tmax 400. frankly, the consideration is
price for me, since i shoot about 5-7 rolls a week and i buy bulk overseas.
my favorite developer is xtol but i also use quite a bit of pq developer, d-76, rodinal and others
(prescysol ef, hc110 etc)
cheers!
