Vax 1, Vax 2, boost:

(Sorry, I wasn’t sure what vax/boost mixes are used outside of the US, so I didn’t (for example) include Astrazeneca options. For all I know the only UK choice is AZ/AZ/AZ.)
No, that’s not how the UK went. For the record - can’t vote - I got AZ/AZ/PF and Mrs T got AZ/AZ/MD. I don’t think AZ/AZ/AZ was ever an option - the intention was to give a different vaccine for the 3rd dose. For younger persons who were guided away from AZ, I assume they got 2 x PF + MD or 2 x MD + PF.

I answered J&J Moderna, but my partner and I are a bit of a special case in that a local San Francisco hospital administered “supplemental” doses of Moderna to J&J recipients that wanted one. The supplemental dose was one of the full Moderna doses whereas the current boosters are half the dose. Hopefully that means I’m that little bit more protected while waiting out the six months for the regular booster.
I’m a 3X Moderna recipient. I got my booster before the rush, and before they had decided that a half-dose would be sufficient. So I got a full dose of Moderna as my booster.
Pfizer Pfizer Moderna for me. My wife has Moderna Moderna Pfizer. I figured we’d mix things up such that both of us had at least the booster of the other. My daughter (nurse) has Pfizer x3.
3M for me.
The only choices were Moderna and Pfizer here, and the former was the only choice at the clinic when I got my first shot. I considered mixing it up with Pfizer, but the data I found suggested they were so similar it wouldn’t matter. So I went for the one with the higher dose, which the studies I’d seen up to that point suggested resulted in longer lasting antibodies.
Later Moderna’s own study on their boosters against omicron came out, and it did seem they had the stronger effect.
Three Pfizer shots for me.

Three Pfizers, but if we need another booster, I’ll try for Moderna. It’s a little tricky since I get injections in my leg so I’ll need a medical clinic (not drive-up tent) with Moderna.
No poll option for J&J boosters? I thought I remembered that being one of the options available to me, though it wasn’t what I actually got.
Australian: AZ-AZ-Pfz
Only because I got my first when everyone was scared of blood clotting with AZ, and they changed the priority system. So my doctor talked me in to one while I was having a routine checkup. They could barely give them away apparently. Even though they are free anyway.
Which, it seems, may have worked to my benefit: Does AstraZeneca’s COVID vaccine give longer-lasting protection than mRNA shots?
I was Pfizer Pfizer and decided to mix it up with a cocktail. Just to hedge my bets and went with Moderna.
Not sure what poke #4 will be 
Pfizer Pfizer Moderna because the CVS was out of Pfizer. Turns out to be a good mix so I’m happy.
American living in China, so I can’t vote in this poll. I got the Sinopharm CNBG BIBP for all three doses.
J&J and Moderna booster (not full dose).
I joined a clinical study, and got something uncommon, so i can’t vote, either.
Pfizer, Pfizer, J&J
Triple Pfizer here.
Yesterday I was diagnosed with a breakthrough infection. Not nearly as bad the second time around, feels like a mild headcold with mild headache and an extra helping of fatigue rather than the hit-by-a-truck/high fever/can barely move of the first go round.
UK - AZ/AZ/Pfz
