If i want to invest in only 1, either elementor pro or astra pro, what would you recommend? If I buy elementor pro, is it ok to go with Astra free theme? or its better to use Astra Pro with elementor free plugin?
I would recommend to buy the elementor pro and use the OceanWp which is free and has more features than the free Astra.
Keep in mind that you pay Elementor Pro for 1 year license. It will work fine after that time but you will not get the updates.
You can try to start with the free elementor and the OceanWP and then if you xant to do some more buy the Elementor Pro
