Also, regarding "capacities" ...
The table saws you mention all come with an inch size that describes the diameter of the blade. It does NOT mention the cutting capacity of the blade. Keep in mind that the nut that holds your saw blade onto the spindle must NEVER make contact with whatever you are cutting, or even the underside of the table. This means that your actual maximum blade height will be limited to around 1/3 of the blade's diameter. If you have a 10-inch saw blade, you might get perhaps 3 and a half inches of blade cutting depth.
Blade quality and tooth count are also important .... rough cutting rip blades are for fast and dirty work. Cleanup is not meant to be easy ... rip it and then plane it and mill it for finished appearance. Cleaner cutting finish rip blades are available. If you find one with carbide teeth, make it one you can sharpen with the proper tool (your table saw equipped with a diamond blade, or a wet-cutting tile saw with a diamond blade and no water). Crosscut and combination blades are generally useful all round, but again get them with carbide teeth. A metal cutting table saw blade might sound useful, but it could be just more economical to buy a metal cutoff saw.
As for band saws .... the "capacity" is determined in two steps. One is in how high the blade guard can rise, which will limit the size of the stock you can rip or crosscut in vertical height. The second is in how deep the throat of the blade stand is, which will limit you in horizontal movement for how wide a piece you can rip or crosscut. The larger the numbers, the longer the blade you'll have to buy for replacements, and generally the more you will pay per blade. Get good quality blades, and an assortment.
You will want rip cutting blades for much faster thinner work that doesn't need details that look nice right away ... You will want finish cutting blades that leave much less cleanup for you to do in sanding before you finish your project... And you will want at least ONE metal cutting blade, just for miscellaneous jobs where you suddenly find that you wish you had something to use other than a hacksaw.
Keep in mind that bandsaw blades can and do break. You'll want a spare or three of your most-used and favorite blades. Don't get cheap ones, you'll pay for that in the number of trips to the store.
Also, I'll echo Terry Q's sentiment ...
A bandsawn edge WILL always need cleanup before gluing, or you WILL see the obvious wide glue lines. For segmenting work, go to the tablesaw and use a fine cutting blade. You will be MUCH happier with the results.
