I have a high end S/VHS player (Panasonic AG-S555) that had a professional service in 2014 before I used it to make uncompressed AVI files for archival preservation from some VHS camcorder tapes via a cheap USB capture dongle (Diamond VC500) and an old version of Adobe Premiere that was able to see the driver.
I don't have an NTSC laserdisc player. I did have a PAL one, but I gave it away before leaving the UK (I only ever owned around 10 discs), figuring that the chances of ever being called upon to play a PAL disc again were so close to zero as to make it not worth the shipping. It could play NTSC discs on a PAL TV, but it didn't read and output a true NTSC signal, and nor did it do a full and genuine signal conversion to PAL-I (so you couldn't record the pseudo-PAL output): I think it just used some form of drop frame processing to f*** with the frame rate and make it work on a PAL TV when hooked up via the built in UHF modulator and an antenna cord. Using a Y/C or composite connection, my PAL TV couldn't play its output from an NTSC disc.
As has been noted above, the large files (about 1.2 GB per minute of running time) created by my VHS transfers did cause a sync problem with the longer tapes (one was of a memorial service that lasted nearly two hours), so much so that I ended up needing to capture the video and audio in separate passes and then resync them.
Laserdisc did have a basic resolution advantage over VHS (425 television lines vs. 240), but a lot of the final, perceived image quality to the end viewer was determined by other factors: the source material used to master the disc or tape, the quality of the mastering itself, and the signal processing in the playback machines. Both formats recorded a composite signal.
