A55/A35 or A54 probably much better. This SD7gen1 dont have much advantage compared to newer mid range exynos. Old SD is not going to give superior experience when compared to new exynos.
https://www.sammobile.com/samsung/galaxy-m55/review/"The Snapdragon 7 Gen 1 is slightly faster than the Exynos 1380 used in the Galaxy M54, Galaxy A54, and Galaxy A35 and around 10-15% slower than the Exynos 1480 inside the Galaxy A55."
"This is a great example of why Snapdragon chips are in so much demand among Samsung fans. They simply have much higher support from game developers right out of the box"
"The M55 is the better choice for passionate gamers when compared with the A35 and A55 that launched a few weeks prior. The M55 only lags behind in thermal management. It doesn't have the large cooling system that sits inside the A35 and A55, so it can get noticeably warm to the touch in long gaming sessions and when it is being charged at 45W. Still, it never gets uncomfortably hot."
"Performance in the camera app is horrendous, though. It lags when you change modes or switch between different zoom levels when shooting videos; it also takes 2-3 seconds to respond to your touches right after you capture a photo or stop recording a video. Combined with the other issues that are mentioned in the camera section above, the M55 is not the least bit suitable for photography enthusiasts."
"In the first half hour, both 25W and 45W charging get you around 50% charge. In 60 minutes, both charge the phone to around 90%. The only difference is that the final 10% charge takes around 10 minutes with a 45W charger and 20 minutes with a 25W charger."
Usually for ODM commission model (most m series and some lower end A series are ODM) samseng will never give a sh*t on camera software department and will not even in OTA updates.
M55 seems like clearing the remaining stock of qualcomm 7 gen1 obviously by ODM on behalf of samseng
