I consider SuSE a huge distribution, good for servers, but too much for a normal user.
PCLinusOS, ubuntu, are small and simpler,
Consider,
PCLOS or ubuntu = 1 CD
SuSE = 5 CD or 1 DVD

Choosing a distribution is not that easy, you have to ask your self what do you want?
A distribution:
- small in size, to fit on a USB stick (choose Puppy Linux)
- small in RAM usage, (choose Puppy Linux, or a distribution that uses XFCE, LXDE, JWM,...)
- a distribution with everything included (choose SuSE)
- a very easy distribution (choose Ubuntu, PCLinuxOS)
- a Windows like distribution (choose something with KDE)
- a cool graphic distribution (choose something that has Compiz Fusion on it)

In the Linux world it's like playing Lego. You have different "blocks" (KDE, GNOME, XFCE,...), different architectures, different bootloaders (GRUB, LILO), distributions are just different ways to assemblate those components. I suggest you to try different distribution and finally you will find what you need.
I have tryed different distro's always thinking this is the best, but then after 6 months my needs changed and i switched.
Everybody has different tastes, different needs, my suggestion try one of those big distro's to begin using Lazarus on Linux, later on when you are more experienced, you will be able to choose.
