Might want to compare the TMs from the
XRM Stats Page. You can simply search for 'TM' without the 's and it wil list all the TM class ships. Unfortunately, it will also list the Terran Atmospheric Lifter, a TL simply because 'tm' appears within any of the text strings.
Most TMs can hold 4 fighters, there's the regular Yaki Chokaro that only holds 3. Those above 4 are the Terran Advanced Macanna which holds 8, the ATF Lofn, which holds 6, and the Yaki Advanced Chokaro, which also holds 6.
As for gun count, you've got the Split Boa tied with the Pirate Caravel at 8 total guns, both ships only have 2 turrets. Of the two, the Boa has the better weapon recharge. The Argon (OTAS) Zephyrus has 6 guns split amongst 2 turrets and main guns. Be warned, I found the weapons generator on the Zephyrus to be incapable of running even 4 PRGs constantly.
When comparing shield strength, the PAranid Helios comes out on top with a max of 4 x 200 MJ shields, followed by a tie for 3x 200 MJ with the Argon (OTAS) Zephyrus, the ATF Lofn, the Teladi Pelican, and the Terran Advanced Macanna.
Feel free to look over the various stats yourself as there's often more to it than just fighter count, gun count, and shielding. Speed and maneuverability is usually somewhat important as well. Then there's shield regen rates. From the look of things, the weapon reactors on these aren't really meant to keep any serious weapons load going continuously, so your fighters are your primary weapon.
Edit: I just noticed that the OP has the stats listed as being current for XRM 1.28, and the stats page itself lists it as being for XRM 1.24. However, I'm fairly certain that the XRM files it reads from are updated with each new release, even if the OP or web page isn't updated to reflect this.
