Peat Pots, or Cow Pots either one are easy to transplant because the entire pot plants right into the soil. They do have a few issues though. They are prone to drying out, especially if you have a lot of pot above the level of the soil - so fill the pots up to the top when you fill them with soil. Set them in a tray, and make sure that the pot gets wet every time you water them - this is how you know you have watered them enough. If you push them close together (so they are touching enough to square off the sides), they'll retain moisture better - but they'll also have issues with roots growing from one pot into another if you do this. I usually do it that way anyway, and spread them out more if it looks like roots are coming through, because we have lived mostly in dry areas where problems with the pots drying out were significant. When you plant them, make sure the entire pot is buried below the surface of the soil also, or the pot sticking above the soil will tend to wick out the moisture from around the plant, and cause problems with drying out the plant during the sensitive transplant adjustment period. If you have too much pot above the surface of the soil, tear it off and throw it in the bottom of the hole before you plant - it will break down and add to the soil.
