Skype is a PC to PC system *only* and uses a proprietary protocol not
compatible with anything else AFAIK. You can buy credit to call landlines
(Skype-Out) but the system doesn't accept incoming calls, although I
believe this is in beta test.
Sipgate uses the well known SIP protocol which is supported and used by
many other systems and is probably the best protocol for compatibility.
The company have had more than their fair share of problems of late which
has put many people off them, but they are working hard to rectify them
and at the moment are relatively stable, although the voicemail system has
a habit of lapsing into German every now and then, but hey I'm learning a
new language ;-)

Not really. If you're using a PC based system they're pretty much
identical IMHO.

As I said before, Skype requires a PC, so the answer to this question is
no. Sipgate (
www.sipgate.co.uk) can use X-Lite on a PC if you want, or you
can use an ATA (Analogue Telephone Adaptor) to plug an ordinary phone in.
Or you can use a dedicated IP phone which has an ethernet connection
instead of an analogue line. Sipgate sell a range of these but IMHO they
are not the best, I prefer the Sipura range. The SPA-2000
(
www.sipura.com/products/spa2000.htm) has two phone ports, which are
separately configurable and can even be on two different providers if you
want, I am very impressed with mine.

You might want to look at
http://voxilla.com which has a lot of useful
info.
