Is there a lot of difference between guestbook 6 and friend for 6 corkboard functionality?

Ok, one is for friends and therefore you have to use the friends function if you want to talk to people in this particular way, whilst the guestbook enables eveyone to have their personal say.

So , i guess my question is if i asked my host to install both to my theme would it look a bit funny design/access wise to see both?

i suppose it would without hacking or what ever the right term is?
