Don't know savage worlds but I do have an independent take on this to offer:
There is decided advantages and disadvantages to starting characters with more "stuff".
I do GURPS 4e, so character customization is always a key point when accepting a player, AND knowing how many points to start the character off will drastically effect the game.
Characters in this system will have the problem of being "samey" to a certain extent in that they will all grab most of the same stuff if only given 90 points. Give them 115 to start and you'll have some nice starting heroes, around 300 and you'll have a super and around 500+ epic, but I have learned one major thing in this:
The key to handing out advantages to start is just to meet the characters with appropriate challenges, and as long as you do that it doesn't matter if you start at level 1 or level 100 as long as your players are capable of acting out such roles.
There is one note on this though:
Characters IN PLAY have less options for min/maxing, so adding in other characters later needs to be done carefully.
Say I make a GURPS char. with 115 points. He's a typical mage with fireball, etc. He then adventures and picks up certain skills that I didn't think the character would ever need at character creation such as leadership, public speaking and intelligence analysis. Stuff that a starting character usually won't pick, or if they do, will pick last and not dump a lot of points in. Instead they'll focus on charging up that fireball to disproportionate levels.
Now as the game goes on, my character now has 165 points and is very well rounded, has lots of back story and is overall a very involved and in depth character heavily invested into the plot. Then we add a new character. He maxes out his fireball, and also buys some magic armor trinkets and pretty makes my character, only better because he's min/maxed from the get go, while I'm a more balanced character that has weathered certain challenges his character should have faced in maturing but simply didn't. He also now shows up my character as a matter of routine as he's just generally more capable, albeit more specialized and can continue to overspecialize because I'm already picking up the slack in all the secondary areas, but am functionally there to play second fiddle, right up until someone ads in a min maxed character that is a specialized diplomat, and now I'm second string entirely.
As a result we need to consider carefully how we add in new characters with exagerated power levels.
I know that's a bit out of the original scope, but I think it's entirely relevant.
