Verdict

No single best speaker here - they are built to different priorities, and the right one depends on your room, your amplifier and what you listen to.

AreaBetterWhy
BassAJBL Studio 6 88LCR digs deeper - 43Hz against 56Hz.
Amplifier needsAJBL Studio 6 88LCR is more sensitive (96dB vs 91dB), so it goes louder on the same amplifier.
Amplifier matchBMartinLogan Motion XT CI XTW6 is the easier load at 8 ohms.
HeadroomAJBL Studio 6 88LCR takes more power (175W vs 100W) - more in hand in a big room.
SizedependsMartinLogan Motion XT CI XTW6 is easier to place; JBL Studio 6 88LCR is bigger, which usually goes with fuller bass. Your room decides.
ExpandabilitydependsNeither adds bi-amping, a sub output or height drivers. JBL Studio 6 88LCR sits in a wider range (15 models), so a matched surround system is easier later.
Priceevenly matchedMuch the same money ($1,600 vs $1,600 a pair).

A JBL Studio 6 88LCR  B MartinLogan Motion XT CI XTW6
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.

Which should you choose?

JBL Studio 6 88LCR has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 56Hz anyway, so judge these on the other rows instead. Match it to your room: we rate JBL Studio 6 88LCR the better fit for a mid-size room and a large room, and MartinLogan Motion XT CI XTW6 for near-field listening and a small room.

And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
