Unless you have wide feet and full tilts don't fit. The OP saw a boot fitter and fits into SPKs instead of full tilts so for him SPKs are better. Both sollys and full tilts have fairly crappy construction in their lower end boot models so I doubt there is much of a quality difference between the two.
Your boot is your most fucking important piece of equipment, and the number one thing (far more important than boot construction or if every 12 year old jibber wears them) is fit.
Your post added nothing useful to the discussion except for maybe confusing any gapers who don't understand boots and causing them to buy full tilt, even if SPKs or dabello or lange or whatever are the better boot for them.
