Labs haven't gotten better in my area sadly to say. IF you do your own lab work for B&W and enjoy it, great. If you are depending on an outside lab, check quality before handing them anything important. Last shot some 4x5 about 2 yrs ago, after not shooting any for about 5 yrs of using digital only. Boy, what I found was not good, actually tried 2-3 labs in area over a two week period and was generally dismayed about poor processing. These were labs that previously did a bang up job on E6 and C41. That is one issue...
On the other side, you can come close to duplicating the grainy look in digital with various plug ins, mean while you know you got the shot, and that except for an errant dust bunnie, with little or no clean up....
Last issue, is and this is argueable, I would only consider using Mf or Lf film these days, digital quality has come along way with current 10-16Mp cameras overall. Even my G7 gives me great prints up to 11x14 as long as ISO is low. Have fun with either way...try out film again, I did and found that it just didn't have the charm that it once did for me [3 decade film user and bw processor and printer]...
