Well first off, they have similar overall hardpoints plus they have a similar design, albeit the EBJ being a lot shorter. I would imagine that most non-extreme or widely used builds could be used between the TBR and EBJ. There are some subtle differences that set them apart though...
The TBR has a higher engine rating to keep with the default 81kph speed and this also shows with the mech's agility. As far as I can make out (without making a direct video comparison), the TBR with its XL375 has the better overall agility compared to the EBJ with its XL325. The EBJ does seem to feel a touch sluggish in its manoeuvers compared to the TBR, it's definitely a little less responsive. Considering how similar these 2 mechs are, I wonder if this is intentional when you look at things from a CW perspective - i.e. Higher tonnage = better agility from the locked engine.
The upshot of the EBJ's decreased agility is that (when empty) the EBJ has 1 ton more to spare compared to the TBR in full armour. However the TBR has 2 additional locked DHS in its engine so if you take that into account, the EBJ is actually 1 ton short on a like-for-like basis. 1 DHS won't make a huge difference but when you're running like for like builds, you may hit that shutdown threshold with the EBJ sooner than you realise if you're too used to your TBR version.
On the battlefield, with its extra agility, the TBR is most definitely the better choice of the 2 plus the TBR appears to have better ST hitboxes. It might be down to the TBR's agility to twist better but I found myself being straight CT cored on the EBJ a lot more than my experiences with the TBR. It may also be the result of the EBJ-PRIME(I)'s geometry as that was the mech I used so my experience with a non (I) EBJ could be a lot different.
Don't forget though that all of my gameplay is based on our revered Pugland as I just can't bear to play CW in any way shape or form. As far as I can see though, within CW the EBJ will be a real alternative to the TBR, nay even a replacement. To get within those tonnage limits it would be an easy choice to make to sacrifice 10 tons or more. However when it comes to pure Pug and what you should choose to make the most impact, I would choose the TBR any day.
For the time being it has no negative quirks compared to the TBR which has negative laser quirks based on how many laser hardpoints it has available. For the vast majority of metas out there, the EBJ will seem like the obvious go to mech now. However the gamers among us who have a shred of intelligence will realise that the longer burn times on the TBR translates to a lower and a more manageable overall heat output, another reason why I actually prefer the TBR. More vomit = more heat

It really depends on the type of build you want to make and which mech out of the 2 is best for it. However when it comes to straight up pugging with a heavy mech, the TBR wins every time for me due to its agility. In CW the slight losses you get from choosing an EBJ outweigh the 10T gains that you make in your drop deck, plus you get the lack of negative laser quirks for all you light saber fans.
As far as a widely revered 65T weapons platform goes though, the EBJ is everything I expected it to be and everything it should be in comparison to what we've had served on our plate so far.
Good job PGI, The EBJ is everything is should be.
