We all have opinions. I suppose it depends on your needs and wants. I want to be able to pull wheels so I can get new tires cheaper than having a shop pull them off the bike. I seldom need this option, but like having it. The Motion Pro box wrench/tire spoon will do the job,
if you have another wrench to use as a cheater. I decided that wasn't good enough for me and just tossed a full size 24 mm combo wrench in the bottom of the saddle bag. I need to add an 8 ounce hammer to beat the aluminum rim into place again if I bend it in the future. At least enough to hold a bead. When I bent my rim in Death Valley, a GS owner loaned me his hammer. Mentioning that a lot of GS guys carry an 8 ounce one for just this reason. Too big and you can do too much damage, so he said.
Stop and go plugs? Well, that's a bit of a choice based on what you really know and understand about them. No glue. <cough> Yep, because they don't bond to the tire. Ever. Sticky strings, with or w/o glue, vulcanize to the tire and become a permanent part of the tire. Run them to the end of the tire life.
Now, if all you want is to get to the next dealer so you can buy a new tire, (because they sure aren't going to patch it for you), Stop and Go mushroom plugs are fine.... usually.... unless a steel belt in the tire at the puncture cuts the plug and it pops out and causes an immediate deflation. Its a temporary repair. If you're good with that, rock on.
What are you comfortable doing on the road? What might you need where you are going? Having a list of the alternative oil filters will make finding an oil filter pretty easy on the road. Oil too, for that matter. Having the tools to pull the filter and dump the oil so you can do it in the Walmart parking lot, then give them the oil to dump is pretty simple.
OTOH, synthetic oil will go a lot longer than the US specified interval. Ever notice that the US spec is 4k miles, but the spec everywhere else is 6200 miles (10k kms)? Hmmm.
Some small vice grips can be used as emergency levers too. And what about that nut/bolt you realize you don't have a socket or wrench for? Adjustable spanner works great for that, (a.k.a. crescent wrench). Decent pliers can come in really, really handy too.
And raise your hand if you forgot that there is a 4mm allen wrench clipped to the underside of the seat to allow you to remove the right side panel and get to your oem tool kit.
Here is a pic of what I carry. Not shown are the three wicked bright LED flashers, the first aid kit, the gallon zip lock of roc-straps and mini ratchet straps with a few bungie cords and a bungie net or the 50' of cord and bundle of 14" zip ties, duct tape, etc.
