I use both a paper and an electronic logbook. I know the CAA are slowly coming into the 20th Century but they used to hold the view that electronic logbooks were the Devil's work and wouldn't accept them. Nowadays they have a better attitude but it is still a lot easier presenting them with a paper version if you ever need to go to the CAA HQ.
The great thing about the electronic logbooks is just being able to 'ask' for the info you require and it being presented quickly and accurately. With this in mind, as a paper version I use the CAA's logbook (CAP 407), which doesn't have a bizzillion columns for multi this, single that but a nice clean layout. If I want to know how many multi hours I have, a quick trip into the electronic logbook and Robert is my Father's brother.
If the choice were only between the two logbooks you've offered I would go for the non-JAR version because it is more logically laid out.
Finally, don't go getting too wound up about the 'correct' logbook for commercial flying. So long as the required information is recorded you could log your flying in a diary if you so wished, so don't necessarily believe the guy with the 25 gold stripes and every gadget known to man in his 'airline pilot' flight bag, who tells you you must get a specific commercial book. Do so, by all means if you wish but if you really wanted to keep your PPL-type going then fill your boots (but do make sure it records all the bits required by the CAA/JAR/EASA/Ministry of Magic, or whatever we're calling them this week.
