Are these 2 coursebooks different?

Coursebook 1: SNAPSHOT - Longman 2000
It has 20 units
Sequence of structures:Present simple-present continuous-past simple and present perfect simple-past simple past continuous and past perfect -future with will/won't, may/might, going to or present continuous-comparison of adverbs and adjectives-comparatives-obligation and prohibition with verbs must, have got to, needn't-1 st conditional-present perfect simple and continuous-2nd conditional- i wish+past tense-used to /be used to-the passive: all tenses-3rd conditional-reported speech-future continuous-future perfect
Coursebook2 : OPPORTUNITIES- Longman Pearson -2000
It has 34 units
Sequence of structures:present tenses-state and activity verbs-used to and would-past perfect- present perfect continuous- the passive- the future- modals of speculation-conditional review:1st and 2nd- conditional 3-wish and should have- reported requests and orders- reported statements- reported questions
Although both books present some grammar topics in a different order, both follow a similar sequence, since both begin witrh present simple and finish with reported speech
The teacher's books don't justify why they chose to follow the order established in both books. They only mention what comes first and what comes next.
Both books offer the same sequence, however, I think that Opporunities would be a good option since it doesn't follow only one story throughout the whole book, (as Snapshot does )it has many different stories in each unit and they deal with interesting topics.
