I have both of these seats. I personally prefer the extend2fit but it depends on your goals. Britax install is super easy. I find the daily use to be fiddly & annoying. The harness seems to get tangled on me frequently & it doesn’t come with a cup holder. I think most people truly love their britax seats, but it just isn’t my cup of tea. The extend2fit has weird square cup holders, but cup holders nonetheless. It also has little buckle holders to keep the harness out of the way when putting your child in. I love this. It’s a small detail but great. It also rear faces to 50 lbs, so if extended rear facing is something important to you, keep that in mind. Britax rear faces to 40 lbs. something also to keep in mind is I believe the extend2fit requires an awkward recline if you forward face before 40 lbs. My very long 20 month old loves the extra leg room with it too. You can also check out Car Seats for the Littles which is a group of cpsts who can help make recommendations for your child/seat installation/car situation too. They’re on Facebook and have a webpage as well. ETA: I think some people find the extend2fit harness difficult to tighten but we haven’t had this issue. Answer from emilybug10 on reddit.com

Britax Marathon ClickTight Review
October 20, 2023 - I’m very torn between the Birtax Marathon/Boulevard Click tight seats and the Graco4Ever. After reading your review, you’ve never lead me astray with anything of your other reviews, I really do lean towards the Britax seats. The headrest issue is what concerns me.

r/beyondthebump on Reddit: Car seats: Graco Extend2Fit or Britax Marathon ClickTight??
February 20, 2019 -
Our LO is a couple months away from outgrowing our infant bucket seat and with Canada’s most incomprehensible shopping holiday just around the corner, we are looking to save a bit of cash on a convertible seat.
I’ve narrowed my choices down to the Britax Marathon or the Extend2Fit. From what I understand, the only real advantage to the Britax Marathon is ease of installation. My family has two vehicles, so being able to occasionally switch the car seat over is a huge asset, but it just doesn’t seem worth paying double the price (or more) for that function alone. Does anyone have experience with these seats?
For reference, one of our vehicles is a 2007 Honda Fit and the other is a 2017 Honda CRV.

I’ve said it before and I’ll say it again… Britax makes a solid car seat. Britax has always been known for its convertible seats, and the “MBA” seats (the Marathon, Boulevard, and Advocate) have always been the brand’s bread and butter. Britax ClickTight convertible car seats make installing your car seat a breeze, but is it a feature you need? Read all about the four seats this feature is offered on.

Britax Marathon review | Car Seat.Org - Carseat, Automobile & Child Passenger Safety Forums
December 22, 2005 - The Britax Marathon is a convertible child safety seat that can be used rear-facing for children 5 to 33 pounds, and forward facing up to 65 pounds, as long as the child's height fits within the highest harness slot height. I have had my Marathon now for over 3 years, and I still love it! So much so, that I wrote a review on Epinions, just because there were so many others that I didn't think were descriptive enough.

April 12, 2017 - What’s so great about the Marathon? Yes, it works to 65 lbs., but there are many seats on the market that work to that spec. Britax’s secret sauce is the seat’s ease of use—from installation to adjusting the harness, the Marathon is a winner.

Britax Marathon ClickTight Convertible Car Seat - Mom vs the Boys
January 17, 2024 - I was able to review the Marathon ClickTight from Britax with my 27 month old. Britax has taken the ClickTight design and made car seat installation a breeze. Literally it takes seconds to install the convertible car seat in the vehicle. With this option I found that no matter who installed the seat I was confident it would be done right with a simple click of the seat belt.
