[Q] Titanium and ROM replacement

[pacut]

Ok, it is clear, as stated into General Q&A:

=========
Will i lose all my texts, apps,etc when i install a new rom?
Yes you will. You could make a titanium backup of everything though and restore it when your done flashing the roms so you can get everything back. Download titanium from the market.
=========

What I don't understand is this: almost all ROM requires wipe data, and this sounds to me settings/data are different among different ROM version. Am I wrong ?

Q1 - If I am not wrong, would a data/settings restore create the same issues like a ROM replacement w/o backup/restore ? At the end, it seems to me, there would not be any difference among backup+ROM replacement+restore and simply ROM replacement without backup&restore

Q2 - would it be better to backup and restore everything (system apps&data, user apps&data) or would it be better to be selective (i.e. only user apps&data) ? What do you generally backup and restore ?

Q3 - assuming a selective backup&restore is the best choice, I would like to know what backup in order to have it safe:
1) contacts' links
2) screens (home & others, in terms of links to applications spread across all the pages)

Awaiting any useful replies from you guys.

Thanks !

i always do a full app/data backup, then when the new rom is settled, do a full app/data + system resotre and then uninstall the apps i dont want.

this will also restore your "desktop" to what it looked like when you backed it up (if you came from the same launcher)

also restores all sms, mms, emails, recent calls etc. this way
