well it can differ greatly if we change the viewpoints.
for a new team great 8 is a league of death as now there are 7 teams which are really good for any new team and if a new team ends up in great 8 now,I am 99% sure that it will end up 8th and relegate without a fight.
for a stable IPBL team,big 8 is stronger because of the amount of competition but lets not forget that indiens and fero are in a rebuilding phase.hardcourt dunkers is in a building phase and all dragoons can loose his cool anytime and buy a couple(or more) good players from the 2.5 mil which he got for selling two of his players.
