Like what? I know Motorola's G Power and the BLU G9 Pro are similarly specced and priced. What else would you recommend that's under the $250 mark?
If you are in the US, the Moto G8 power is the obvious straight contender.
If you're in Asia, there are too many phones to consider at that price point. Here are some of the options at that price range in my country, Indonesia.
There's Realme 6 with 90Hz screen, Mediatek G90T, UFS storage, and actually costs slightly less than the TCL.
There's Xiaomi Redmi Note 8 Pro, also with Mediatek G90T, 128GB UFS storage, also costs less.
There's Samsung Galaxy M31, which cost slightly more but comes with 128GB of UFS storage and larger 6000mAh (!) battery, and the Samsung brand.
There's also Oppo A91 with weaker Mediatek P70, but 128GB UFS storage and 8GB(!) of RAM.
There's then Vivo Z1 Pro with SD712 and 128GB UFS storage.
I keep mentioning UFS storage because the TCL 10L uses the slower older eMMC storage. As for camera, I would consider all the phones in this price range to be similar, pairing a high res main camera with an ultra wide and then with useless low-res depth sensor/macro camera.
Personally if I'm in the market of $250 phone, my eyes would be on the Samsung M31 (for the 6000mAh battery) or the Realme 6 if one really wants that higher refresh rate screen.
So far TCL only sells TVs and air conditioning in my country.
The mobile phone competition here is definitely much tougher.
