Replacing FitBit and Getting My Motivation Back! Advice Needed

Since coming out of the pandemic, I've wanted to get back into basic daily fitness walks and begin swimming/using the gym on occasion. I'd love to begin hitting step goals again and tracking basic exercise through a wearable device, as I found it very motivating when I first bought a FitBit a few years ago. My Charge 3 isn't working out and I am looking for opinions on quality FitBit alternatives-- HUGE bonus if they are MyFitnessPal compatible.

I think the biggest thing putting me off is the customer service/decreased quality in the app ever since Premium was introduced. After my Charge 2 stopped working due to no fault of my own and the disappointing response I got from customer service, I was going to switch brands but I was gifted with the Charge 3 on my birthday. Within a year, I found steps were being recorded inaccurately, I got dead pixels that now make step count impossible to read, have consistent app crashes, glitches with the watch face randomly staying black for days at a time, constant syncing errors, and other quality-of-life issues that have put me off using it regularly. Plus when the app does work for me, all the features I loved to use (challenges, solo walking adventures) are buried under Premium features that I am not interested in.

What are good quality FitBit alternatives that you have used? I am looking for something that:

• Accurately records steps, heart rate, sleep
• Is preferably waterproof (benefit, not requirement)
• Has a clear time/date display that also shows step count
• Has a reliable app with good connectivity and customer support
• Is reasonably priced
• Has customizable straps and can look professional when needed

I am not picky but I will not use certain brands like Huawei or Amazon, as they are notorious for data concerns (yes I am aware most are selling data but some companies are worse than others and I currently live in the UK where it is more strict).

I do not use messaging or music features and am not interested in in-depth fitness analytics. I did like how FitBit had a MyFitnessPal-esque food tracker but this is not essential, especially if the MyFitnessPal app is compatible for syncing. Motivation to move was a huge part of what I loved about FitBit but it is hard to stay motivated when the product isn't consistently working and paid subscriptions are pushed and promoted over quality service.
