These are 2 great cameras, you won't go wrong with either one. Here's what this happy Wehman owner (and never-Phillips-toucher) thinks are some important issues. Phillips users, correct any errors, please.
1. Bellows length. If you shoot with a 600mm or do macro stuff, Wehman wins.
2. Bag bellows. W. doesn't offer one, and the supplied bellows is restrictive with very short lenses like a 110mm. Whereas Phillips...?
3. Bomb-proofness. W. absolutely has it, I believe more than P.
4. Rear swing. W. has geared asymmetrical rear swing, a real luxury in a reasonably priced camera. If you aren't already, it will make a (rear) swinger out of you.
4. Front shift and swing. W. controls both with a single knob that is okay in a pinch, but is less than optimal. If P. has a more convenient design, and you use such front moves, this could matter.
5. Price, availability, esthetics, etc. You decide.
One thing I have discovered about W. is that if you stick to shorter lenses (in my case up to 355mm), you can leave the front extension plate in the car, and go shooting without it, which lowers the weight and bulk, and also makes the camera faster and easier to use.
Best of luck with your decision.
