Short answer: the JBL COL600. It ranks #13 of 23 column and line array PA speakers by sound quality, rated 3.3/5, at $386; the JBL CBT 50LA-1 ranks #17, rated 3.1/5, and costs $585, so there is little reason to consider the other one.
What the JBL COL600 does well: Manufacturer measurements give a 6.11 preference score with an ideal subwoofer and a 2.1dB reference band from a 598mm column only 93mm deep. The catch: Bass measures 106Hz at -3dB and about 78Hz at -10dB, and output tops out at 111dB, so it is for speech and background music.
Why pick the JBL CBT 50LA-1: A Constant Beamwidth Technology column from the same JBL CBT range as the measured JBL CBT 70J-1 and JBL CBT 1000, with eight 2” full-range drivers in a 528mm tall cabinet. The tradeoff: No independent measurements yet, so it can’t be compared with ranked PA speakers.
Buy the JBL COL600. It is rated higher for sound quality than the JBL CBT 50LA-1 and costs less, which makes it the one to get unless you need something the other one does better.
Worth knowing: the JBL CBT 50LA-1 has not been measured yet. Its rating is estimated from related models, with a likely range of 2.7 to 3.5, so treat this verdict as provisional.

JBL COL600: $386.00 Passive B&H Photo Video eBay
Same family: the JBL COL800 (larger model, ranked higher, rated 3.4/5).
Pros: Manufacturer measurements give a 6.11 preference score with an ideal subwoofer and a 2.1dB reference band from a 598mm column only 93mm deep. Two racetrack woofers and a 1-inch tweeter give 160° x 110° coverage with a 10° downward tilt, and a 70V/100V transformer or 8 ohm direct mode suits restaurants, shops and meeting rooms. Measured bass extension of 106Hz (-3dB).
Cons: Bass measures 106Hz at -3dB and about 78Hz at -10dB, and output tops out at 111dB, so it is for speech and background music. The data is manufacturer supplied, rated low quality, and the standalone score is 2.64.

JBL CBT 50LA-1: $585.00 each Passive Estimated Amazon eBay
Same family: the JBL CBT 70J-1 (larger model, ranked higher, rated 3.4/5), the JBL CBT 100LA-1 (larger model, ranked lower, estimated 3.1/5), the JBL CBT 200LA-1 (larger model, ranked higher, estimated 3.2/5) and the JBL CBT 1000 (larger model, ranked higher, rated 4.1/5).
Pros: A Constant Beamwidth Technology column from the same JBL CBT range as the measured JBL CBT 70J-1 and JBL CBT 1000, with eight 2” full-range drivers in a 528mm tall cabinet. It keeps a steady 150° horizontal and 20° vertical pattern across frequency, which helps speech intelligibility in reverberant rooms, and JBL rates it at 115dB continuous.
Cons: No independent measurements yet, so it can’t be compared with ranked PA speakers. Its 2” drivers have no separate woofer or tweeter and roll off below 80Hz, so music needs a subwoofer, and it requires an external amplifier.
