I have a Hohner Crossover, a Suzuki Manji and a couple of Seydel Session harmonicas that I've been playing for a couple of months.  The Blues Harp has a great, throaty sound that is perfect for the blues.  I love it.  You can play single notes fairly easily on this harmonica.  However, it is probably the least comfortable harmonica I have played.  I've tried adjusting it, but that doesn't really fix the problem.  I have pretty much decided on using the Seydel Session harmonicas - they are easier to bend and the most comfortable harmonicas I have played.  Seedy Session harmonicas have a kind of muted sound, which is nice and bluesy.  The Hohner Crossover is kind of brassy and the best sounding harmonica for my taste.  The Blues Harp is kind of in the middle.  The Manji also has a nice sound, a lot like the Hohner Crossover, but It is a little temperamental; some of the reeds freeze up and don't blow.  The Crossover is a great harp and can do anything that you want it to - if you are really good and if you can adjust the reeds - but it isn't as easy to play as the Seydel Sessions.  If you can master it, the Crossover is a great sounding harmonica, but if you need a little help, the Seydel Sessions is simply the easiest to play harmonica I have found.  To sum up, the Seydel sounds great and is the easiest and most comfortable harmonica I have played.  The Blues Harp is not comfortable to play, but it does sound great.  It may not be as responsive as some harmonicas, but hey, I'm not Jason Ricci; this harp is better than me.  If you just want to jam some blues, this is harp will work.  It is built solid, it sounds great and is a blast to play.  The Manji is a great sounding harp, but kind of temperamental and needs some adjustment.  The Hohner Crossover is the best sounding harp I have ever heard, but you need to adjust the reeds and it is a little more difficult to play than the Seydel Sessions.  The Crossover is more comfortable to play than the Blues Harp, but not as comfortable as the Seydel Sessions.
