Each person sees things differently. To categorize custom bows as better than production is silly. Custom bows are generally fancier; exotic woods, riser bends, et al. As for shooting, very few of them will shoot any better than a Martin Hunter, or Bear Super Kodiak. The biggest thing that separates todays bows performance against vintage bows is fastflight string....not better builds.
Some folks get their shorts tightened when someone suggests that their "custom" bow many not be any better at shooting arrows than an old vintage Hoyt, Bear, Browning, etc. Fact is, in most cases they aren't any better....just costlier and prettier (subjective).
A great bow, will shoot where you want it to hit, and be comfortable to the enth' degree. That may be a $1500.00 Black Widow, or a $70.00 Ben Pearson Hunter.
