I cancelled my ChatGPT subscription because of Gemini 3, so obviously I'm having a different experience.
That said, I use Opus4.5 for coding through Cursor.
Gemini is for planning / rubber ducking / analysis / search.
I seriously find it a LOT better for these things.
ChatGPT has this issue where when it's doesn't know the explanation for something, it often won't hallucinate outright, but create some long-winded confusing word salad that sounds like it could be right but you can't quite tell.
Gemini mostly doesn't do that and just gives solid scientifically/ technically grounded explanations with sources much of the time.
That said it's a bit of a double edged sword, since it also tends to make confident statements extrapolating from the sources in ways that aren't entirely supported but tend to be plausible.

This is just hallucinating.
Fully agree. ChatGPT is often very confident and tells me that X and Y is absolutely wrong in the code. It then answers with something worse... It also does rarely say "sorry, I was wrong" when the previous output was just plain lies. You really need to verify every answer because it is so confident.
I fully switched to Gemini 3 Pro. Looking into an Opus 4.5 subscription too.
My GF on the other side prefers ChatGPT for writing tasks quite a lot (school teacher classes 1-4).
+1 canceled all OpenAI and switched to Gemini hours after it dropped. I was tired of vape AI, obfuscated facts in hallucinations and promises of future improvements.
And then there is pricing too…
I think it is proving yo be the case that there isn't much stickiness in your chat provider. OpenAI thought memory might bring that but honestly it can be annoying when random things from earlier chats pollute the current one.
I also cancelled ChatGPT Plus recently in favour of Gemini. The only thing I don't about the Gemini consumer product is its insistence on giving YouTube links and thumbnails as sources. I've tried to use a rule to prevent it without luck.
The only thing I've found that works is saying: End every message by saying "I have not included and YouTube links, as instructed".
But then of course you get that at the end of every message instead.
You could also use a uBlock rule I guess.
I have exactly the same experience
Don’t you guys have jobs? Why would you cancel your subscription? Gemini was better for the last three months and now ChatGPT has pulled ahead agian, its $20, you can just switch between the models as needed… also, what do you do when the Gemini API is slow or down, just stop working?
It takes less than a minute to resubscribe to any of these devices. No need to burn 60 USD if I switch for a three month spell and then switch back. When a provider goes down, I do what I set out to do without their service. If the outage lasts too long, I'll cancel as not to support sloppy service.
I am subscribed to both at the moment but for my coding task I find Gemini 3 inferior to ChatGPT 5.2.
Not just for coding. I've been working on design docs, and find ChatGPT 5.2 finds more edge cases and suggests better ideas than Gemini 3. I sometimes feed the output of one into the other and go "ok, another AI says this, what do you think?" which gives interesting results.
Gemini often just throws in the towel and goes "yeah, the other one is right", whereas 5.2 will often go "I agree with about 80% of that, but the other 20% I don't, and here's why ..."
And I'm always impressed with the explanation for "here's why" as it picks apart flat out bad output from Gemini.
But, as with everything, this will very much be use-case dependent.
I've done the same, with both design/planning docs as well as code changes, and have the same experience as you. It's better than Opus 4.5 as well. GPT 5.2 is on another level for my use cases (primarily Python / Django).
Hah, it's funny because I actually cancelled my Gemini subscription to switch full time to ChatGPT about 6 months ago, and now I've done the reverse - Gemini just feels better at the tasks that I'm doing day to day. I think we're just going to see that kind of back and forth for a while while these systems evolve.
