Why do you want a mountain bike for riding around London primarily (assuming you mean roads?), as especially on a budget bike, the fork will be a liability (weight, bounciness and maintenance) vs a rigid one. They look very similar, so the fork should be the bit you pay attention too if you're stuck on an MTB (versus a rigid fork flat bar or gravel type bike with drops)
 
Wow those specs are so close in many ways. Also I noticed they both have Deli Mizt tyres which are a common tyre fitted to Polygon bikes so don't be surprised if the Carrera is actually made in Indonesia by Insera Sena as well. Polygon is Insera Sena's own brand for their bikes. So you are probably looking at very similar bikes of very similar quality. I would try to get to both stores to look at both bikes. Also look to how you can improve the price. For me I noticed I have Go Outdoors on halifax reward account so I get 7% off if I buy using my Halifax credit card or debit card. There may also be voucher codes to use and cashback sites to go through. Often you can get ways of reducing the price at Halfords once you work out what discounts you get the prices could be wider apart.

Try to work out what you need from a bike though. I mean I personally would hate to have all the weight of suspension forks and the maintenance they require if I'm using the bike mainly on the road. Suspension forks look cool in the showroom but can get annoying pretty quickly unless you need their functionality.

Halfords do a Carrera Subway bike which delivers a better all round package being much better on the road and still great for light off-road use and brilliant for gravel etc. Probably the most versatile bike going although I'm sure some gravel bike riders will disagree but the Subway is still capable of doing lighter mountain bike trails which a gravel bike couldn't do. Remember most of your weight is at the rear of the bike so the benefits of front suspension are really about going off-road.

It's a lot of money so worth spending a bit of time thinking about how you are going to use the bike. It will be slow on the road compared to most other bikes as fairly heavy and low geared. It will be ok as a beginner proper off-road bike. I totally understand often half the appeal of a bike is how it looks and really you can't go wrong with either bike.
 
+1 for a hybrid with a rigid fork.

If you're going to be doing the vast majority of your riding on tarmac, then you'll not want to be riding something that gives you the constant feeling of riding through treacle. It's the quickest way to frustration on a bicycle.

At that price point, the suspension fork will be a very basic one, which will be more of a hindrance than a help. And unless you go to the other extreme, i.e. a flat bar road bike, there will be more than enough "give" in the tyres on a hybrid to tackle gravel or dirt trails. All you need to do is lower the pressures some for riding off road, and then pump the tyres back up again for riding on tarmac.

A decent "commuter" type tyre should meet all your needs here - good puncture protection, and a slick centre with a lightly treaded or slightly knobbly shoulder.
