Second baby on the way! Double stroller question!

Graco family over here! We have a graco car seat and stroller currently and love them both. We have an almost 2 year old (Feb. 1st) and a second due August 2021! I know it’s early but something to save/plan for is a double stroller for us!

Here are a few I found and want to know some pros cons from experienced parents with more than one kiddo!

With a toddler and an infant - did you use the double stroller?

Stay with a single stroller?

With double strollers there are options for two seats or one seat with the sit/stand part! Which one would be better?

Here are a four I found with good reviews / could be an option! Plus a pic of my little munchkin!

Thanks in advance :)

Looking into them further, the Modes, duo has the most flexibility for what we are looking for. The most similar to my joggers flexibility in a double stroller! Still planning on looking at it in person but it’s the one I’m leaning towards atm!

Watching graco’s videos are super helpful!
