I don't want to come off as a total dick, but...(and since I feel guilty for chasing you off the BMarket capsule buy thread...)
At the level of "stellar" performance alot of gear is finally evaluted subjectively-- it might make sense to build to G7 circuit/body and debut it w/ different capsules, through the same mic pre for consistancy, like the M1 (or the G9 to provide a review of that pre's capabilities as well.) There could be recordings posted for each using acoustic guitar, vox both male and female, guitar amps and etc. You could also experiment with grill combos also. I'm hoping, once I actually get it together , to post some wavs doing just this.
It could also be easier to answer your question, Shane, if we knew what you anticipate using the mic for. Since there's not, nor will there ever be, one mic that records all sounds well, or even likeably well, if the question were posed qualitatively you might get more useful responses.
In any case I'm not sure one capsule over another will be a waste of money. You query seems economically motivated, so it's fair to ask how much are you prepared to spend on one capsule?
Jazzypidday seems to like Peluso's CK12 capsule better than the Blue Cactus capsule: an opinion that will save you $250. JP hasn't mentioned what he's recording or how, if the mic is for guitar, if he uses proximity effect, if the mic is a room mic, a drum overhead, male vox, female vox, etc. To date I don't think anyone has used the Kiwi or Plum capsule. The Kiwi is visually intriguing, plastic clamps.

Don't forget, stuffing a G7 into a mass produced mic limits, to a degree, your grill options. The B2 Pro might seem like a bargain until you want to change the head grill or when a client wrinkles her nose up at a B'inger mic on the stand. An MXL would fair better, image wise, than a B'inger; your image is on the line here as well. A mic handmade to look like a Tele would generate some intrigue; a B2 could very well generate disdain. AFAIK Gus just used the capsule and mount, at very little savings over a Peluso capsule and mount, since I'm assuming he chucked the body. Economically it might serve you to purchase some tools to make mic bodies with rather than shoving your mic into someone elses mic, know what I mean? Presumably you would make more if you liked what you ended up with, or you would make several with different capsules to fill different needs. The Blue capsules do seem like a bargain, especially if you got your braggin' rights and told people the mic was fitted with a Blue capsule. Given Blue's prices, i.e., you could buy a very nice used car for the price of two Blues, compared to the price of build a G7 or variant, & that includes a primo tube like a vintage Tele EF86 (estimating total cost w/Blue cap and primo tube plus the project at just under $1K,) your attention to the physical details and appearance of the mic could pay off in spades. A B'dinger mic will never get you that kind of credibility.
