One of the reasons I am posting this is also to see if I overlooked some obvious considerations.
Edit To Add; Forgot to mention, I have a full size Craftsman router (which I will likely replace or supplement with a full size Bosch soon), so I am buying this as my second router for smaller projects.
One obvious consideration that wouldn't have been 30 years ago, but is a very much viable option now, with lithium ion, is the convenience of cordless.
If you do get the Makita trim router, you will find that Makita's LXT 18v XTR01 Cordless Router easily and perfectly interchanges will all of the accessories, bases, guides, and parts that Harry shows on his workbench in the photo above. I in fact have both the cordless and corded version of this Makita trim router, and can personally attest to the interchange of all bases and parts at the working end of the router. Plunge base, tilt base, offset base, etc... all work seamlessly between the cordless and corded Makita.
I had purchased the cordless first, for the freedom and convenience of not having to dance around with a cord getting caught or cut. I ended up buying the corded kit because, as Harry illustrates, it included so many doo dads and accessories, it was cheaper to buy the entire kit on sale than it was to buy each individual accessory base, as accessories are rarely discounted as deeply as competitively priced tools and kits. So essentially, I got a free corded router and case, for the price of the accessories I would have purchased to outfit my cordless router anyway.
Rob Robillard, who runs A Concord Carpenter and Tool Box Buzz, did a comparison of five cordless trim routers, and found the Makita to be the smoothest and most precise. It was not the most powerful or fastest in the tests he conducted. It was however, the second highest in value, and the third highest overall. It lost points for not being as cheap as the Ryobi, or as powerful as the DeWalt. The Bosch Colt was not compared.
If you do go with the convenience of cordless, the battery platform that you are already on will likely weigh heavily in your selection.
But the ultimate litmus test is how the router fits in your hands, as the tool becomes an extension of your hand when doing the work.
To any and every extent possible... try before you buy. Don't forget to seek out smaller independent tool stores, rather than just look to what Lowes may have. Lowes doesn't carry Makita or Milwaukee or Ryobi. Neither Lowes nor Home Depot stock much in the way of Bosch, although they do carry a limited selection of Bosch branded products, mostly in the hammer drill and bit line. It will take some effort to get your actual paws in contact with the routers you may be considering.
But the consideration that I thought you might be overlooking is the convenience and nimbleness of cordless.
