John asked a simple question and got many replies,why it has to be a debate is crazy.There are many different manufactures of front suspension kits available,choises can be made base on the type desired or cost.They all will do the job.Just be carefull of some of the early ones made that had steering and geometry issues.Most all on the market today have been sorted out and work well.
Just to throw my opinion out FWIW if your building a race specific car the lightest weight,easyist to install and most problem free would be a strut front end.It also gives you the option to set the wheelbase and trackline where you want it.This option give you varable deminsions for wheel,tire size and any other clearence issues.It will be custom to your specific application.
