Help me choose a linear actuator

[Kapitonov]

Hi! I want to put myself a linear actuator on the sliding gate to the cottage. I looked in the internet, there are a lot of offers and the prices are very different. Maybe there are people here who understand this and can advise me what type of actuator is better, manufacturer and where to buy? I will be very grateful.

Gate weight 150 kg. Gate width 3.4 m.

I choose between https://www.haroldbeck.com/actuators/42/model-42-109/ and https://www.actuatorzone.com/electric-linear-actuator
