It is all subjective my friend. some folks love the hit of McDermott, some might like an old Meucci, some would not give up their Tascarella custom; every single person has their own likes and dislikes when it comes to cue "hits" and cue construction components from tip to bumper.
In my opinion there is no general answer because every poll ever done on this site as to favored cue or cue maker gets hundreds of different responses. I , personally, have had positive and negative feelings about certain production and custom cues - I cannot say there is a general answer to your question. My best advice is spend $75- buy the book "Play Great Pool" by Mark Wilson. Once your stroke meets his challenge in the book, you are then ready to worry about the hit of a production cue vs. custom cue- which is a question that cannot be answered the same by all anyhow.
I firmly believe that a pool stroke has to meet very, very high standards before one can really begin to fully understand the effect that one very good cue vs. another very good cue will have on their game. How a cue "feels" in your hands is one thing to consider; and how YOU feel the cue helps you to COMPLETE a very pure pool stroke is another major aspect - defined as the "hit".
A "custom" cue can be made to the specifications that you have learned through experience help a cue to feel its best in your hands ( weight to the 10th of an ounce, weight distribution- balance, type of wrap or lack thereof, etc.) The effect on the cue ball " hit" and feedback to your body upon stroke completion, might also be tailored and fine tuned with such things as hardness or softness of tip, ferrule material, shaft material ( wood, carbon fiber, LD), then you have shaft taper, joint construction and material used in that joint construction, wood selections, etc. etc.
NO GENERAL ANSWERS! Sorry- it is all personal trial and judgement until one settles on their favored choices in all of the above.
