Strength wise, about the same. However, if you load and unload the splice over time, the straight bury can work itself out. I've seen it happen quite often on trap lines. Usually resulting in a broken tiller extension...
i have yet to have an eye splice fail after it being lock stitched
I also learned long ago when i fall overboard for any reason (broken trapwire, overly slippery sunscreen on legs that have gone wrong, etc) .. hold the mainsheet (for dear life) but dump the tiller extension (so far i have about a 50/50track record with remembering to dump the stick)
