Thermal clips can sometimes be prone to explode whereas standard can't without prolonged exposure to heat. Solid ammunition can be more damaging than thermal ammo; plus more options can be allowed with solid ammo. Tracers can be good in the right situation whereas thermal rounds can harm the wielder. Both solders have an excellent amount of experience but I have to go with the old-school style of Nathan Hale since his artillery won't explode unless damage or prolonged heat exposure is in use.
