After doing a bit more research and video watching, I still have two visit a dojo. I'm actually more interested in "comparing" Jeet Kune Do and Shorinji Kempo... I've looked at Aikido and just felt it could offer more for what I was looking for, although the idea of using someone else's moves to cause them to fail is interesting.
Okay… first thing I'd caution against is trying to compare in the first place.
The thing to realise with martial arts is that they're not teaching you "moves" or "techniques"… they're teaching a tactical, unified, coherent method of addressing combative problems. It's like trying to compare pizza and hamburger… then compare them with ice cream and a roast beef. All are good… and people will have certain preferences… but there's nothing that makes a hamburger better than a roast… or pizza more appealing than ice-cream.
Jeet Kune Do and SK are at the top of my list now. Does anyone have thoughts on these two, side by side? What are the similarities and differences? Does JDK have any philosophical elements? Does it include meditation and usage of pressure points and healing?
In a way, JKD is nothing but philosophical elements… that's kinda it's raison d'être, really…
As far as similarities and differences, well, even that's not particularly easy to go through… JKD is sometimes taught (or described as) "JKD Concepts"… it's really, more than anything else, a particular approach to a personal exploration and study of martial arts. To that end, the particular make-up (on a technical level) of a particular JKD instructors methodology is as much a product of their varied training backgrounds as it is to do with JKD itself. Yes, there are certain aspects that can be expected to be found across the varied lineages and forms, but just because one JKD instructor has a heavily FMA influenced approach, there's little reason to expect the same in someone who doesn't share the same lineage and teachers.
The Shorinji Kempo place may concentrate on meditation and healing, but the chances of that are very low. JKD, from what I know, doesn't. If you're looking at that, you will probably need to try an internal martial art.
Now here's something that has stuck out at me through this thread… there have been mentions of looking to Kosho Ryu Kenpo, comments of "I'd recommend Shorinji Kenpo, but that's a personal bias", and so on… and, to be honest, I personally feel that people here are confusing Shorinji Kenpo with the various American "Kenpo" systems, such as Kosho Ryu (James MItose and so on… hmm…) and so on. And, honestly, no, it's nothing to do with that at all.
Shorinji Kenpo is a Japanese system founded by Doshin So… a person of some controversy, to say the least… who developed the system based in a range of established arts, primarily karate and judo methodology, and used it to put forth his particular brand of Buddhism… as a result, if the Shorinji Kenpo school does not have an emphasis on spirituality, religious aspects, meditation etc, then it's not Shorinji Kenpo. As a result, the odds are not "very low" at all.
To do a contrast, not to compare "this is good, this is not", but to indicate just how different these systems are, here are some clips:

Now, in the interest of full disclosure (well, close to it, anyway), I am in no way enamoured of this system… I find it to be an example of some of my least favourite aspects of modern (particularly Western) arts… and I see such an array of flaws and issues that I'd personally steer clear completely… but that's likely largely due to my Japanese art background…

This is Shorinji Kenpo… quite different to the American versions in a number of ways, really….
One of the best documentary series on martial arts ever, and it's episode on Shorinji Kenpo. Watch this repeatedly to get some idea of what it's about…
As far as which you should study, eh, that's up to you… the one that you'll continue to attend, really. Visit, watch, make up your own mind, and enjoy!
