3 inch lift and level options

Ok, for starter my truck is an 09 Tacoma sr5 package 4x4 6 lug i4 manual. Now, with that being said. Should I go with 5100 bilstien up front and blocks in the rear? Or should I go with spacers up front and blocks in the rear? They come out to be about the same in price. I can do all the work myself at work. I'm a mechanic, so this should be a cake walk. There are pros and cons to both of them. I also have the TSB 4 leaf spring in the rear already done. What size blocks should I get? Thanks
