well, the in-line is subjectively more elegant and does not require a T fitting to connect. Apart from that, they are for all intents and purposes the same.
NTC sensors are not exactly the most precise of devices anyway, that's why Aquasuite allows you to set some offset on the temperature sensors.
Chose the one that intergrates better in your loop
In that case, I prefer plug type at additional ports of pump top or reservoir because in-line temperature sensor is easily pulled out from the fitting. Thanks alot!
