What the differences mean
Weight
The Asics GT-2000 15 is 20g lighter, at 275g against 295g. As a rough guide every 100g costs about one percent in running economy, so 20g is worth a fraction of a percent. You will feel it more than it costs you, and it counts for more on a fast 5k than on a slow long run.
Heel drop
This is the real difference. The Brooks Adrenaline GTS 25 has a 10mm drop and the Asics GT-2000 15 has 8mm. A higher heel asks less of your achilles and calf and more of your knee, and a lower one does the opposite. If you get regular trouble at one of those, pick accordingly. If you get none, pick whichever is closer to what you already run in, because changing drop suddenly is the most reliable way to give yourself a new problem.
Support
The Brooks Adrenaline GTS 25 has proper support built in and the Asics GT-2000 15 is neutral. That matters if your ankles roll inwards noticeably when you run. If they do not, support is not a bonus, it is just something you do not need underfoot.
Price
£134.99 against £145 at full price, so the Asics GT-2000 15 is £10 less. Both are discounted often enough that the gap on the day may look nothing like this, which is worth checking before you decide on price alone.
Which should you buy?
Neither, until you have tried both on. Fit decides more than any specification on this page, and the two shoes above are close enough that a foot shape will separate them faster than a spreadsheet will.
