Worth it is so subjective... If you look at retail value,
I am sure that themore expensive bike is worth it. The real question is whether the difference is worth $200 to us, your respondents...
In my opinion, Either bike would do fine for your purposes (similar to my own).
One significant factor is 8 vs 10 speed... 8 speeds is plenty (that is all I have ridden for thousands of miles)... and you will actually have a wider gear range with the lower end bike because of the triple front.
Hydraulic versus mechanical disks... Everything I have heard is that hydraulic brakes are better, but you can adjust mechanical with standard tools, and never have to bleed them. Either one of them should stop you fine as long as they are maintained properly.
Any drive train components on bike shop level bikes will perform well enough for most casual riders, although higher end will sometimes feel more precise, and possibly be a touch better at shifting, and usually be lighter and/or polished better.
Bottom bracket is largely irrelevant other than the fact that the type needs to match the cranks used... and since it is a prebuilt bike, I am pretty confident that they will be the right type.
The more expensive bike will probably be slightly lighter than the cheaper bike due to component choices. Probably not enough to be noticeable when cruising, but possible a bit detrimental on climbs, or if you need to pick your bike up to put it away, or on a rack.
If I were picking between these two, I would probably save the $200 and put it toward a nice destination ride later in the year.
