I've had the pleasure to try all of these out as part of a switch tester. I'll give a quick overview of my thoughts on each switch below. My daily drivers are Boba U4 Silent Tactile, 62g, for reference.
**TTC Bluish White:**
Nice crisp bump, slightly more tactile than an Ocean Blue, but the bump is not as long or overwhelming as a Boba U4. There is a little bit of travel post-bump, and the bump itself starts pretty much at the top. There is almost no wobble, and even unlubed it feels pretty smooth. The sound is muted a little when pressed down, but they're not nearly as silent as the U4s and the upstroke still produces a clack, so I'm not sure if this is a silent enough switch for the office. Overall I really like this switch! At $0.77/switch, they seem to be living up to the price.
**TTC Mute Red:**
Speaking of silent, I can be very brief that I did NOT like the Muted Red switch. It feels extremely mushy and the entire down- and upstroke are scratchy. It may improve when lubed, but for less money you can pick up a very nice set of Bobagums if you want silent and linear. I'd definitely skip this one, especially compared to how smooth the other linears feel stock (bit of a spoiler).
**TTC Speed Silver:**
When comparing these with other switches, the shorter travel time is very noticeable. I find that I make a lot of accidental presses when I try linear or shorter travel time switches, so when combined, it's definitely not a switch I would personally use. Also don't have the ability to make use of the 'faster response competitive gaming' aspect. However, these are very smooth switches, and they produce a satisfying deeper sound compared to TTC Gold Pink, TTC Heart, and Akko CS Linears. $0.95/switch is a steep price though.
**TTC Gold Pink:**
A very light switch, when comparing it directly to Akko CS Vintage White, these feel definitely more premium (which is good, at almost 2.5x the price). This seems to be mostly due to almost no wobble, almost no scratchy sound while unlubed.and an overall smooth operation. Where the Vintage White has noticeable spring ping on the upstroke, this Gold Pink produces a nice clack. It's a little high-pitched but overall very satisfying. at$0.74/switch, I think these are my second favourite of the bunch.
**TTC Gold Blue:**
Don't have any other clickies to compare it to, because I've never had the need to become public enemy number 1 at the office or at home. The click/bump is positioned right in the middle of the downstroke, much lower than the bump on the Bluish White. The click is loud and crisp, and due to the position there's plenty of post-travel to avoid bottom-out, while not being as eager as a speed switch. Stem was a bit wobblier than other TTC switches in this list, and I just really don't like clickies, but despite that, I didn't hate them as much as Mute Red ;). At $0.77/switch you'll probably have to refer to a clicky enthousiast if this is worth it over other loud switches like the Kailh Box Jade and Navy.
**TTC Heart:**
The most expensive switch at over $1 per switch!!! Is it worth it? Not really in my opinion. Pros: there is absolutely no stem wobble in any direction due to the cylindrical box stem design. Also, they're completely transparent, so that should work great with any RGB or color theme you might want to go with. The heart inside the stem that they get their name from is cute, but it only works with a north-facing LED position, otherwise they're inverted. It also doesn't really add anything unless you have transparent or translucent keycaps to go with it. That leaves the way the switch operates. It's smooth enough, though slightly scratchier than the TTC Speed Silver or Gold Pinks. The sound is also quite dull, a bit deeper like the Speed Silver but muted somehow, despite it not being a silent switch. It's a shame because it really can't afford to be sub-par at this price level.
**Conclusion:**
TTC Bluish White, Gold Pink. Speed Silver get a thumbs up!
Gold Blue and Heart get a maybe, as someone else with niche interest might enjoy their characteristics more.
Avoid Muted Red.
