When you are comparing console handheld hardware for your living room, the two listings that often end up side by side are the M15 4K 64G Game Stick and the Retro TV Stick 64G. Both are 64GB retro game sticks, and both come with two wireless controllers. The M15 is listed at USD 20.66, and the Retro TV Stick is listed at USD 18.99, so the price gap is about $1.67. The bigger question is what you get for that difference.
Quick verdict
The M15 is the one to pick if you want a console with a larger listed game library and an audio tech feature. The Retro TV Stick is the pick if you want the lower listed price and a dual-core CPU mention. Both support two-player gaming right out of the box.

Where each product wins
The M15 is the stronger pick if the larger listed game library is your priority. Its listing also describes a Linux Retroarch open source system, which may appeal to players who like tinkering with emulation. The Retro TV Stick wins on price, with the lower listed number, and its description calls out support for PS1, ATARI, and MAME formats. That gives it a clearer retro-format checklist. So if you want the bigger library and an open-source approach, lean toward the M15; if you want to save a little on the listed price and have a defined format list, the Retro TV Stick is the one.
Product notes
M15 4K 64G Game Stick

The M15 listing points to a 30000+ game library and 3D Audio Technology, which makes it the higher-capacity pick in this pair. The description adds a Linux Retroarch open source system, which should be appealing if you like emulation variety. Its color is white, and the description says two wireless controllers come in the box, so two-player sessions are possible without extra purchases. The tradeoff is the higher listed price of the two, and the listed connectivity is HDMI, so you will need an HDMI-compatible display. If the larger game count and the audio feature outweigh the extra cost, this is the listing to choose.
Retro TV Stick 64G

The Retro TV Stick listing is the lower-priced of the two, and it adds a dual-core cortex-A7 CPU to the attribute list. Its black shell is a clear visual departure from the M15's white, and the description says it can connect to a TV, computer monitor, or projector, which is helpful if you want flexible screen options. The description also names support for PS1, ATARI, and MAME formats, giving this console a defined retro-format checklist. The caveat is the built-in game count: the title lists 20000+ games, which is smaller than the M15's 30000+, and the description mentions multiple game-version choices, so the exact total can vary by version. If the lower listed price and the format support matter more than the extra games, this is the one for you.
Final choice by use case
If the listed game count and audio features are your priority, choose the M15 4K 64G Game Stick. If you want to stay at the lower listed price and prefer a black console, go with the Retro TV Stick 64G. For two-player nights, both are ready to go.
