Well some things to note is that CFs do have a massive endurance advantage, particularly if you use the Strat ops bonus.
CFs get 160 points per ton, with Strat ops you can make this 320, though fusion powered CFs get this as well if they only spend "safe" thrust (in this case one could say that their less efficient with their overthrust/"after burners"), though by in large it should not be to hard not to use their "overthrust" out side of low altitude combat situations (I.e high altitude map speed limit of 3...).
So a Meteor HSF with it's 3 tons of fuel can have as much as 960 points of fuel (equivalent to 12 tons for an ASF). So it can say fly 3,000ish km to a target and stay their all day waiting for a call in.
Though as stated in comparison to ASFs their slower, more fragile and have a lower flight ceiling.
An ASF can reach anywhere in the world in two hours or less (thanks to being orbital capable), a CF even at 3,240kph (roughly mach 3, speed 3 on the high altitude map) will need upwards of five to eight hours to reach anywhere on a world (depending on the diameter of the world).
Though in a quirk of the rules flying at velocity's that are not a 2x multiple of the velocity used to generate them is less efficient, I.e. the max speed of a CF on the high altitude map is 3, to maintain that speed requires 2 thrust points, 3 is not a multiple of 2 (as 4 is). As such the max range at a velocity of 3 for the Meteor HSF with it's 3 tons of fuel is ~25,900km, If it went at a velocity of 2 (or if it could 4) it would have a range of ~34,500km.
In short not going exactly 2x your thrust rating will drop your range to about 75% of the nominal maximum, this also applies to ASFs.
Though CFs do have the advantage of being some what more agile.
