Skype or Vonage for VOIP?

i'm getting voip (unlimited in and out calls)

skype is $29.95 + $38 per year for unlimited in and out calls.

Vonage is $24.99 X 12. w/e that is

for skype i need to get the wireless phone that doesn't need a pc. i'm getting the Philips VOIP841 for $128 on amazon.

which is better? based on my past experience w/ skype pc to pc, i know it's pretty much crystal clear as long as u have a good internet connection. i have 500KB/s (4Mb/s) cable with Time Warner (i'm in buffalo, ny)

which should i go with? i'm thinking skype, but i want to hear some other opinions.

thanks
