Not sure that I would use PVC decking for a porch. But I've been very happy with TimberTech XLM for my deck.

Thanks for your reply dennisgli. Are you suggesting you wouldn't use PVC on the porch because it can be slippery? Or for some other reason?

The surface of XLM is very hard - but it is textured enough that I don't consider it slippery. Though it probably isn't as non-slip as my fir porch floor.

I guess I wouldn't use it on a porch because my porch is pretty "traditional" - and I think wide, plasticky boards just wouldn't look right. Maybe it would look OK on a more "modern" porch - though I'm not sure what I mean by that!

XLM is pretty much maintenance free - I just wash it with soap to get the dirt off. They warn you not to put rubber things on it because it will stain but I haven't had that problem.

If you leave the ends exposed you'll need to do something to finish them since the inside is a different material and has voids. You might be able to just paint it to match?

Hope that helps.
