I have my bias in metallic-based tints that are not so common in the market. They are some cheap one BUT for me, a good metallic based tints used high quality metallic sputters and those don't come cheap. So my preference would have been

1. VKool Elite, 55, 35, etc, very durable and lasting. Excellent heat rejection but as you noted, the price shoot so high that I cannot afford it anymore. It is worth the extra bucks if you are rich tho...IMO.

2. 3M Crystalline for clear tint but got 1 great weakness that I cannot accept. Smart tag....that I need to pass multiple each days.Yeah, I have RFID but those tolls in Kesas, some RFID very long queue or worse, someone got stuck inside have to reverse. So no smart tag, no go for me. Other than that, it would have be in my preference if I go for clear tints. Like VKool, there are a lot of fakes out there tho...some got cheated fake and complain 3M not working as it should be, so watch out and go for trusted installer if you go for this.

3. Irispro....why, coz I looking for VKool replacement at lower pricing. Metallic based tints. Local homegrown company tho with multple main branches in key cities. This one has about 3/5 of the price of VKool. Worked excellent in heat rejection and coloring. Just a bit thick and have slight white haze under certain sunlight angle. Loves the heat rejection tho as I have expected (or above my initial expectation). Surprisingly VLT 30 at rear is dim but not dark (bright enuf to avoid phobia)...Like the dim slight bluish purplish lighting in the car. Very nice. Pricy tho if you compare with other ceramic-based tints but for metallic-based tints and extra features they have, it should be on par with other premium tints. Metallic based tints with good metals are usually higher pricing than ceramic. Metal sputter cost more money to produce..hehe. Smart tag friendly similar to VKool.

4. Raytech is also a good brand, ceramic-based tint. Quite pricey tho vs other brands. However their highest range Ultra 70 for fws not smart tag friendly. So out it goes for my preference. Their 2nd range tho is smart tag friendly but I always prefer maximum heat rejection for clear or near clear tints.

Others, I can't comment coz no experience in them. Skip surveying them in-depth coz not metallic-based tint due to my preference.

Getting my tesla model 3 today, initially planned to get full 3m crystalline but is it ok for condo cards?
Alternative brands i was suggested was llumar, is it ok with smarttag?
Irispro is aa good as 3M and smarttag compatible?
