Compare Model 3000 to Model 1000

So far we have an old Baun Braun Oral-B Professional Care 500 Electric Toothbrush (successor to the Professional Care 6000) in use, but since the battery to run out, it is time for a new bathroom.
The new Braun Oral-B D20 TriZone 1000 and Braun Oral-B TriZone 3000 were available.
But is it worth the premium for the Braun Oral-B TriZone 3000?
Since both models differ only slightly the first "general"
What I noticed positive:
Handset>
- Good battery, ie the charge lasts a long time. Up completely Landen I come to about 7 days (2 times a day and for each just over 2 minutes)
- Faster intervals compared to previous models
> Compare Care Model 500 = 7,600 rotations; 20,000 pulsations / Model Model 1000/3000 = 8,800 rotations // 40,000 pulsations / min.!
-Optical Pressure sensor
- The old "classic" essays are also attached to the handpieces, is important for the children's essays.
Model 3000: 3 Verschidene programs to choose from
1. Cleaning (normal program) / 2. Sensitive / 3 System. Brighten

Brushes>
- Good cleaning performance, even in the interdental spaces. (I find this personally better than the Oral-B Precision Clean)

Total>
Model 3000: storage for 4 brush is included.

What struck me negative:
Handset>
- No "Inovation" with the previous models, but rather a development behutsamme
Model 3000: Only one button for all functions, in other words I have to press the one button several times to get to the desired function
Model 3000: This is only one button to operate there, I have to press to turn off the button longer or turn the "Programs" = impractical
Model 3000: no big difference the programs
Brushes>
- Suitable to the size for children
- Model 3000: Here are two brush heads with it, but no colored rings to distinguish, very bad, chaos is inevitable when several used the toothbrush

Conclusion 1: The Model 1000 and 3000 have a good cleaning performance in the verbiendung with new essays.

Conclusion 2: want to have strong buy recommendation for the new 1000 who unbediengt a storage box and a number of programs to choose from resorts to 3000th
I personally would have wished with 1000 storage, the Währe Perfect.

And as always: Who "unhelpful" clicks, this should please comment.
Thanks
