depends on your main preference, room size, throw distance and ambient light control
1 - if 3D is your main concern, and with such a huge image size, you would definitely need all the lumens you can get.. so the obvious choice would be the very bright LV
2 - for 150 size, you need to calculate if your room can support this size with the projector distance calculator.. maybe your room could accommodate or maybe its smaller, you should check. if its smaller, then you probably can do well with the 25e and save money
3 - your room needs to be a proper bat cave for this size screen to work without the image washing out.. if its a dedicated theater room, then you are well on your way with even the 25e.. however for ambient light or watching in living room, you would be better with the LV
4 - LV is much more costly, and also, the replacement bulbs are also a lot more costly than the cheap 25e ones.. if you would be watching a lot on your projector, yu would be replacing bulbs every couple of years or quicker and cost would add up..
if your screen size ends up smaller due to calculations, you would be equally happy with the 25e.. if you have ambient light in room, and need full 150, go for the LV.. you can always dim the LV to 25e, but you canot bump the 25e to LV..
