It's going to depend on what you want to do with this design. Honestly, I think the pattern on the left is very busy - but for some, that might just be exactly what they want in a custom deck. Some people will love a bordered card, or a thin-bordered card, or no border at all.
Who and/or what are YOU aiming for with this design?
Without knowing that, all the questions just add up to "design by committee", which rarely brings a desirable result. I'm not saying disregard your potential customers, but I am saying find your vision and bring it to fruition.
If the Pedale Design/Misc. Goods deck was brought to the Design/Dev board for tips and pointers from the peanut gallery, a lot of people would have picked the design apart, saying how awful it was, whatever. Many people were saying negative things about it at first on the Playing Card board, and I was among them, though eventually the design did grow on me. Meanwhile, it blasted the previous deck project fundraising record out of the water by tens of thousands of dollars - and that now-dethroned project itself had broken the previous record by tens of thousands of dollars! The only design input he took from anyone was in regard to his court cards having indices in mismatched corners, which he corrected simply by flipping the art on some so they now all have left-corner indices.
I'd wager that only a small number of Discourse or UC members even invested - but the designer had a vision and he looked BEYOND just the card-collecting community to fulfill it. It paid off in spades. He didn't ignore his customers, but he did maintain the core of his vision from day one.
