Great thread, and great topic.
I like this response, by @Piglet
While some of us are more focused on looks and others on sound, in the end, we can’t help ourselves from being influenced by how they look to some extent.
After starting with an Easttop 008k, which I loved, I decided to try different harps from different companies. One of the complaints I heard from many people is how difficult it is to identify the key on poorly marked harps. As such, I thought it would be much easier to just have different harps for each key to test several out.
I brought the kids together for a family photo 
Having different styles and colors makes it easy to find my “Harp for the Day”, which goes as follows:
Monday - Lee Oskar - A
Tuesday - Rocket - Ab
Wednesday - Baby Fat - Bb
Easttop 008k - Bb
Thursday - Golden Melody - C
Friday - Special 20 - Db
Saturday - Conjurer - G
Sunday - Golden Melody - C
For now, I repeat my Golden Melody on Sundays, until I get a new harp 
While they all sound a bit different, I’ve noticed each has its own character:
The Lee Oskar does well up and down, though is a bit more challenging on the bends for me.
The Rocket 
has the most Bad Ass Sound on the low end and plays well throughout.
The Baby Fat makes up for my blown 4 blow on my Easttop 008k and both sound pretty decent.
My Special 20 in Db, also known as Oops, was my previous favorite harp, but she blew the 4 draw while I was playing her signature song, SHOWTIME, the other day when I realized the song has exactly 212 notes, which for some reason seems significant to me, but I’m not sure why.
The Conjurer is my cheapest harp, costing just over $10 and is surprisingly good, except for a 7 blow, which just seems a bit off to me, though it measures well on the Bend-it tool
The prettiest harps for me are the Golden Melody and The Conjurer, which also both feel very good in my hands. The Easttop 008k is beefy and feels solid, with its sleek black on silver finish. The Baby Fat is just plain cute and very discreet in most circumstances.
So for me, I would say that yes, LOOKS DO MAKE A DIFFERENCE, but it is the SOUND that causes our pulse to quicken, and sends our soul to soar.
