F-106 stealth-modified and Maneuverability strengthened version with upgraded digital flight control and more realistic aerodynamics, intended for a cheap version of stealth aircraft, and it's a fairly old design. It's featured on supersonic performance compared with F35.
F106 primer plus Stealth strengthed version concept, developed from earlier F-106 stealth project. Canard and vertical stablizers are all cancelled. Stealth performance greatly improved. Thrust Vectoring is increased to 35 degrees.
It uses large strake wings like F-18 early version, and the strake wings are straight-lined to ensure its stealth performance.Interestingly, vertical stablizers are replaced by side air brakes located on the tail and sides of the plane.
For supersonic performance, the attack angle of strake wings itself should be optomized for about M1.5 flight. In another word, the strake wongs should not be flat, bit should have an attack angle to optimize supersonic performance.
The extra large strake wings with an extra attack angle itself serve as lift generator in subsonic areas, and it helps supersonic trimming, too. It doesn't have the same radar reflection rate like canards, but could serve as similar performance like canards when being supersonic.

The air brakes are used as both air brakes and rudders.
Maneuverability did not fell a lot compared with Canard version of F106 plus.Based on @Sharkdude300 's https://www.simpleplanes.com/a/mKAsh2/F-106A-Delta-Dart
