If you think so, you've to state what the power use was of the chipsets you've used.
For example the well-known nRF51: https://devzone.nordicsemi.com/f/nordic-q-a/1657/how-to-mini.... It can be as low as 20 uA. Between advertisements 4 uA.

LTE-M is a high(well couple of kilobytes per second) bandwidth, full duplex, high duty cycle transport layer. Not only that, its relatively long distance (well kinda)
Bluetooth is short range < 30m, and at high bandwidth shorter range. yes it can be full duplex, but not at low power (I've not validated that claim though) The BLE beacons don't emit a location every 4 seconds, they also don't have a GPS on all the time eating 35mah.
Lora has a maximum duty cycle of something like 5% (ie it has to be not transmitting 95% of the time) not only that, its not designed for realtime two way communications, It's niche is a sensor reporting the state of a sensor every n minutes.
You just basically say so by explaining how much higher the bandwidth is.
The thesis of the author of this article still stands. It's not just GPS.
"This mobile tracker is seemingly designed to resemble a popular Bluetooth tracker and sports a LTE-M radio and GPS receiver. But as mentioned here and here, a leopard can’t change its spots."
They try to be as low power as a Bluetooth tracker, but they just can't. It will never be actually low power.
On two AA batteries, 10 years. It's plural.
