Let us not even get into BD versus Pakistan in economy as there is simply no contest:
1. GDP per capita - BD is at 2000 US dollars versus 14000 dollars for Pakistan
2. GDP per capita growth - BD is at 6-7% and Pakistan is at 1-2%
3. Debt to GDP ratio - BD is at 28% and Pakistan is at 73%
As for industry BD domestic companies dominate the home market in terms of IT, shipbuilding, pharmaceuticals and electronics.
Pharma has been growing exports at 15% a year over the last decade and is now really starting the push into Western markets with regulator approval given.
TVs in the electronics sector are now being sold to countries such as Germany - see below of Hyundai using BD as an original equipment manufacturer to import into India:

"According to a deal signed on Monday, Walton as an original equipment manufacturer will supply 1 lakh units of refrigerators and 20,000 residential air-conditioners to Hyundai Electronics."
BD is in the midst of an infrastructure boom(circa 6% of GDP) and all the ingredients to sustain the economic growth are coming online or are being constructed - power stations, roads, railways and ports.
The whole world is beating a path to BD's door to invest in the 100 Special Economic Zones that have or are being build.
Sorry but all that Pakistan has going for it is to be propped up by China and the Arabs - of course they will extract their price for this.
